Robert Brain traces the origins of artistic modernism to specific technologies of perception developed in late-nineteenth-century laboratories. Brain argues that the thriving fin-de-siècle field of “physiological aesthetics,” which sought physiological explanations for the capacity to appreciate beauty and art, changed the way poets, artists, and musicians worked and brought a dramatic transformation to the idea of art itself.

For more than two thousand years, almost all doctors in the West used bloodletting to treat a great variety of diseases and conditions. In an attempt to find out why they acted thus, Dr Brain has translated the three works on bloodletting by the second-century physician Galen, which provide by far the most comprehensive account of the practice in antiquity. This is the first published version of these works in a modern language. After a brief summary of Galen's medical (...) system, the author goes on to consider the origins of Galen's ideas and methods, with particular reference to the Hippocratic writings, and the question why Galen, in common with most of the ancient physicians, believed in the efficacy of the comedy. The effects of bloodletting are considered in terms of modem physiology and medicine, and the possibility is explored that it may indeed have been beneficial in the conditions prevailing in Galen's time.

This paper traces the dramatic proliferation of leadership roles in English primary and secondar schools, due mainly to central government education policy of the past two decades. This has transformed schools from relatively simple to highly complex organizations and has impacted on the working conditions of, and demands on, teachers, together with many aspects of schooling. These changes are illustrated with typical examples of schools' leadership structures and their functioning. Interview data provide teachers' views on, and reactions to, the changes (...) in school leadership. The paper also reviews the ways in which teacher education institutions have responded in terms of providing initial and in-service education and training to equip the profession for this new and developing challenge. It examines the reception of such programmes by teachers and the reported impact on schools' management and the role of leadership within it. (shrink)

The world of work is being changed at an unprecedented rate as a result of the rise of the Fourth Industrial Revolution. This rate of change was accelerated by the COVID-19 pandemic, which left organizations and their leadership to deal with myriad of challenges. These changes also impacted leaders’ identities in their work and their roles in their organizations. We examine how leaders responded to the various workplace challenges presented by the COVID-19 pandemic and what this meant for their work (...) identities as leaders. To do this, we made use of role identity theory, social identity theory, and leader identity. A qualitative study was conducted with a group of eight senior leaders from various South African and global organizations who had between five and 10 years’ work experience, and some had even more. Data were collected through semi-structured interviews, conducted virtually and in person. Thematic analysis was used to analyze the data. The main finding that emerged from the research was that leaders employed virtual leadership to ensure that customers’ expectations were met, and to manage team-and organizational performance. These leaders achieved this by fostering a digital culture and building effective teams. They achieved their leadership goals by ensuring social identity continuity amongst their teams. This required them taking on extra roles, such as strategist, technology expert, entrepreneur, coach, mentor, and member of the team. Their leader role identity, as part of their work identity, was amplified by the pandemic. The implication is that organizations should develop leadership development programs to increase and strengthen leader identities to capacitate them for times of crisis. (shrink)

Neurite orientation dispersion and density imaging is a diffusion model specifically designed for brain magnetic resonance imaging. Despite recent studies suggesting that NODDI modeling might be more sensitive to brain development than diffusion tensor imaging, these studies were limited to a relatively small age range and mainly based on the manually operated region of interest analysis. Therefore, this study applied NODDI to investigate brain development in a large sample size of 214 subjects ranging in ages (...) from 0 to 14. The whole brain was automatically segmented into 122 regions. The maturation trajectory of each region was characterized by the time course of diffusion metrics and further quantified using nonlinear regression. The NODDI-derived metrics, neurite density index and orientation dispersion index, increased with age. And these two metrics were superior to the DTI-derived metrics in SVM regression models of age. The NDI in white matter exhibited a more rapid growth than that in gray matter. These diffusion indicators experienced conspicuous increases during early childhood and the growth speed slowed down in adolescence. Region-specific maturation patterns were described throughout the brain, including white matter, cortical and deep gray matter. These development patterns were evaluated and discussed on the basis of NODDI’s model assumptions. To summarize, this study verified the high sensitivity of NODDI to age over a crucial developmental period from newborn to adolescence. Moreover, the existing knowledge of brain development has been complemented, suggesting that NODDI has a potential capability in the investigation of brain development. (shrink)

I review the brain disease model of addiction promoted by medical, scientific, and clinical authorities in the US and elsewhere. I then show that the disease model is flawed because brain changes in addiction are similar to those generally observed when recurrent, highly motivated goal seeking results in the development of deep habits, Pavlovian learning, and prefrontal disengagement. This analysis relies on concepts of self-organization, neuroplasticity, personality development, and delay discounting. It also highlights neural and behavioral (...) parallels between substance addictions, behavioral addictions, normative compulsive behaviors, and falling in love. I note that the short duration of addictive rewards leads to negative emotions that accelerate the learning cycle, but cortical reconfiguration in recovery should also inform our understanding of addiction. I end by showing that the ethos of the disease model makes it difficult to reconcile with a developmental-learning orientation. (shrink)

An influential view of the nature of the language system is that of an evolved biological system in which a set of rules is combined with a lexicon that contains the words of the language together with a representation of their context. Alternative views, usually based on connectionist modeling, attempt to explain the structure of language on the basis of complex associative processes. Here, I put forward a third view that stresses experience-dependent structural development of the brain circuits (...) supporting language as a core principle of the organization of the language system. In this view, embodied in a recent neuroconstructivist neural network of past tense development and processing, initial domain-general predispositions enable the development of functionally specialized brain structures through interactions between experience-dependent brain development and statistical learning in a structured environment. Together, these processes shape a biological adult language system that appears to separate into distinct mechanism for processing rules and exceptions, whereas in reality those subsystems co-develop and interact closely. This view puts experience-dependent brain development in response to a specific language environment at the heart of understanding not only language development but adult language processing as well.

Ample evidence from various quarters indicates that the perceptual-cognitive competence of the pre- and perinatal human being is significantly greater than was once thought. Some of the evidence of this emerging picture of early competence is reviewed, and its importance both as evidence of the biogenetic structural concept of “neurognosis” and for a theory of enculturation is discussed. The literature of pre- and perinatal psychology, especially that of developmental neuropsychology, psychobiology, and social psychophysiology, is incorporated, and some of the implications (...) of these data for a theory of enculturation are suggested.

The size and organization of the brain are determined by the activity of progenitor cells early in development. Key mechanisms regulating progenitor cell biology involve miRNAs. These small noncoding RNA molecules bind mRNAs with high specificity, controlling their abundance and expression. The role of miRNAs in brain development has been studied extensively, but their involvement at early stages remained unknown until recently. Here, recent findings showing the important role of miRNAs in the earliest phases of (...) class='Hi'>brain development are reviewed, and it is discussed how loss of specific miRNAs leads to pathological conditions, particularly adult and pediatric brain tumors. Let‐7 miRNA downregulation and the initiation of embryonal tumors with multilayered rosettes (ETMR), a novel link recently discovered by the laboratory, are focused upon. Finally, it is discussed how miRNAs may be used for the diagnosis and therapeutic treatment of pediatric brain tumors, with the hope of improving the prognosis of these devastating diseases.

A high percent of oxidative energy metabolism is needed to support brain growth during infancy. Unhealthy diets and limited nutrition, as well as other environmental insults, can compromise these essential developmental processes. In particular, iron deficiency anemia has been found to undermine both normal brain growth and neurobehavioral development. Even moderate ID may affect neural maturation because when iron is limited, it is prioritized first to red blood cells over the brain. A primate model was used (...) to investigate the neural effects of a transient ID and if deficits would persist after iron treatment. The large size and postnatal growth of the monkey brain makes the findings relevant to the metabolic and iron needs of human infants, and initiating treatment upon diagnosis of anemia reflects clinical practice. Specifically, this analysis determined whether brain maturation would still be compromised at 1 year of age if an anemic infant was treated promptly once diagnosed. The hematology and iron status of 41 infant rhesus monkeys was screened at 2-month intervals. Fifteen became ID; 12 met clinical criteria for anemia and were administered iron dextran and B vitamins for 1–2 months. MRI scans were acquired at 1 year. The volumetric and diffusion tensor imaging measures from the ID infants were compared with monkeys who remained continuously iron sufficient. A prior history of ID was associated with smaller total brain volumes, driven primarily by significantly less total gray matter and smaller GM volumes in several cortical regions. At the macrostructual level, the effect on white matter volumes was not as overt. However, DTI analyses of WM microstructure indicated two later-maturating anterior tracts were negatively affected. The findings reaffirm the importance of iron for normal brain development. Given that brain differences were still evident even after iron treatment and following recovery of iron-dependent hematological indices, the results highlight the importance of early detection and preemptive supplementation to limit the neural consequences of ID.

Volume II in the Evolution of Gestalt series, _Relational Child, Relational Brain_ continues the development of the paradigm shift that places human development in a field that is deeply complex and fundamentally one of interconnection, taking us away from the limiting view of us as separate individuals. It builds on the foundation of contemporary views of relational neurodevelopment and the profound influence of relationship on brain growth. It shows how, particularly in the first two years of life, (...) but continuing across the whole of childhood and adolescence into early adulthood, the relational field is the context of child development. The focus then broadens out to examine the intersubjective influence of community, culture, and social and physical support. Backed by neurobiological and related research, it offers many examples of relational Gestalt practice with children, adolescents, and their families, with stories of loss, trauma, isolation, and other adversities. Not just an invaluable resource for child and adolescent therapists, _Relational Child, Relational Brain_ goes beyond the Esalen Study Conference from which it emerged and is a further invitation and challenge to apply relational Gestalt practice as a coherent and effective way forward in the troubled world of today.

What is attention? How does it go wrong? Do attention deficits arise from genes or from the environment? Can we cure it with drugs or training? Are there disorders of attention other than deficit disorders? The past decade has seen a burgeoning of research on the subject of attention. This research has been facilitated by advances on several fronts: New methods are now available for viewing brain activity in real time, there is expanding information on the complexities of the (...) biochemistry of neural activity, individual genes can be isolated and their functions identified, analysis of the component processes included under the broad umbrella of "attention" has become increasingly sophisticated, and ingenious methods have been devised for measuring typical and atypical development of these processes, from infancy into childhood, and then into adulthood. In this book, Kim Cornish and John Wilding are concerned with attention and its development, both typical and atypical, particularly in disorders with a known genetic etiology or assumed genetic linkage. Tremendous advances across seemingly diverse disciplines - molecular genetics, pediatric neurology, child psychiatry, developmental cognitive neuroscience, and education - have culminated in a wealth of new methods for elucidating disorders at multiple levels, possibly paving the way for new treatment options. Cornish and Wilding use three specific-yet-interlinking levels of analysis: genetic blueprint, the developing brain, and the behavioral-cognitive outcomes, as the basis for charting the attention profiles of six well-documented neurodevelopmental disorders: ADHD, autism, fragile X syndrome, Down syndrome, Williams syndrome, and 22q11 deletion syndrome. Their overarching aim in this book is to provide the most authoritative and extensive account to date of disorder-specific attention profiles and their development from infancy through adolescence.

US Supreme Court rulings concerning sanctions for juvenile offenders have drawn on the science of brain development and concluded that adolescents are inherently less mature than adults in ways that render them less culpable. This conclusion departs from arguments made in cases involving the mature minor doctrine, in which teenagers have been portrayed as comparable to adults in their capacity to make medical decisions. I attempt to reconcile these apparently incompatible views of adolescents’ decision-making competence. Adolescents are indeed (...) less mature than adults when making decisions under conditions that are characterized by emotional arousal and peer pressure, but adolescents aged 15 and older are just as mature as adults when emotional arousal is minimized and when they are not under the influence of peers, conditions that typically characterize medical decision-making. The mature minor doctrine, as applied to individuals 15 and older, is thus consistent with recent research on adolescent development. (shrink)

Today, one out of every six children suffers from some form of neurodevelopmental abnormality. The causes are mostly unknown. Some environmental chemicals are known to cause brain damage and many more are suspected of it, but few have been tested for such effects. Philippe Grandjean provides an authoritative and engaging analysis of how environmental hazards can damage brain development and what we can do about it. The brain's development is uniquely sensitive to toxic chemicals, and (...) even small deficits may negatively impact our academic achievements, economic success, risk of delinquency, and quality of life. Chemicals such as mercury, polychlorinated biphenyls, arsenic, and certain pesticides pose an insidious threat to the development of the next generation's brains. When chemicals in the environment affect the development of a child's brain, he or she is at risk for mental retardation, cerebral palsy, autism, ADHD, and a range of learning disabilities and other deficits that will remain for a lifetime.We can halt chemical brain drain and protect the next generation, however, and Grandjean tells us how. First, we need to control all of the 200 industrial chemicals that have already been proven to affect brain functions in adults, as their effects on the developing brain are likely even worse. We must also push for routine testing for brain toxicity, stricter regulation of chemical emissions, and more required disclosure on the part of industries who unleash hazardous chemicals into products and the environment. Decisions can still be made to protect the brains of future generations."In his crisply written, deeply documented book, Dr. Philippe Grandjean, renowned physician and public health specialist, describes the exquisite vulnerability of the developing human brain to toxic chemicals in the environment, a vulnerability that he ascribes to the brain's almost unimaginable complexity. Today, nearly one in 6 children is born with a neurodevelopmental disorder - a birth defect of the brain. One in 8 has attention deficit disorder. One in 68 is diagnosed with autism spectrum disorder. These rates are far higher than those of a generation ago, and, although they are less publicized, the problems are more prevalent than those caused by thalidomide in the 1960's. The increases are far too rapid to be genetic. They cannot be explained by better diagnosis. How then could they have come to be? Dr. Grandjean has a diagnosis -- the thousands of toxic chemicals that have been released to the environment in the past 40 years with no testing for toxicity. David P. Rall, former Director of the US National Institute of Environmental Health Sciences, once stated that 'If thalidomide had caused a ten-point loss of IQ rather than obvious birth defects of the limbs, it would probably still be on the market'.

A substantial portion of the human genome has been found to consist of simple sequence repeats, including microsatellites and minisatellites. Microsatellites, tandem repeats of 1–6 nucleotides, form the template for dynamic mutations, which involve heritable changes in the lengths of repeat sequences. In recent years, a large number of human disorders have been found to be caused by dynamic mutations, the most common of which are trinucleotide repeat expansion diseases. Dynamic mutations are common to numerous nervous system disorders, including Huntington's (...) disease, various spinocerebellar ataxias, fragile X syndrome, fragile X tremor/ataxia syndrome, Friedreich ataxia and other neurodegenerative disorders. The involvement of dynamic mutations in brain disorders will be reviewed, with a focus on the large group caused by CAG/glutamine repeat expansions. We will also outline a proposed role of tandem repeat polymorphisms (TRPs), with unique ‘digital’ genetic distributions, in modulating brain development and normal function, so as to generate additional mutational diversity upon which natural selection may act.

Both Notch and NFκB signaling pathways are well‐known for regulating proliferation, differentiation and apoptosis. Recent studies have presented several lines of evidence supporting an integration of the Notch and NFκB signaling pathways in differentiation/maturation of a diverse range of cell types. It is notable that Notch and NFκB signaling pathways share many common features: (i) both are activated by common stimuli such as TNF‐α and hypoxia, (ii) activated Notch (NICD) and NFκB mediate transcription by regulating corepressors such as SMRT/N‐COR, and (...) (iii) both regulate similar target genes such as Hes‐1 and IκBα. This review expands on how the collaboration between these pathways may play an important role in the CNS. We will speculate on the mechanisms by which Notch and NFκB signaling may collaborate to regulate stem cell renewal and differentiation during brain development and function.

Comparing expression patterns of orthologous genes between insects and vertebrates, we have recently proposed that the ventral nerve cord in insects may correspond to the dorsal nerve cord in vertebrates. Here we show that the early development of the insect and vertebrate brain anlagen is indeed very similar. Insect and vertebrate brains express similar sets of genes in comparable areas with similar functions in the adult. In addition, early axogenesis establishes surprisingly similar patterns of axonal connectivity in both (...) groups. We therefore propose that insect and vertebrate brains are built according to a common ground plan, and that specific areas of the insect and vertebrate brains be considered as homologous, meaning that these areas already existed, with their specific functions, in their common ancestor.

The Drosophila embryo provides a useful model system to study the mechanisms that lead to pattern and cell diversity in the central nervous system (CNS). The Drosophila CNS, which encompasses the brain and the ventral nerve cord, develops from a bilaterally symmetrical neuroectoderm, which gives rise to neural stem cells, called neuroblasts. The structure of the embryonic ventral nerve cord is relatively simple, consisting of a sequence of repeated segmental units (neuromeres), and the mechanisms controlling the formation and specification (...) of the neuroblasts that form these neuromeres are quite well understood. Owing to the much higher complexity and hidden segmental organization of the brain, our understanding of its development is still rudimentary. Recent investigations on the expression and function of proneural genes, segmentation genes, dorsoventral‐patterning genes and a number of other genes have provided new insight into the principles of neuroblast formation and patterning during embryonic development of the fly brain. Comparisons with the same processes in the trunk help us to understand what makes the brain different from the ventral nerve cord. Several parallels in early brain patterning between the fly and the vertebrate systems have become evident. BioEssays 26:739–751, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

Recent studies suggest that the tetracycline antibiotic minocycline, or its cousins, hold therapeutic potential for affective and psychotic disorders. This is proposed on the basis of a direct effect on microglia‐mediated frontocortical synaptic pruning (FSP) during adolescence, perhaps in genetically susceptible individuals harboring risk alleles in the complement component cascade that is involved in this normal process of CNS circuit refinement. In reviewing this field, it is argued that minocycline is actually probing and modulating a deeply evolved and intricate system (...) wherein psychosocial stimuli sculpt the circuitry of the “social brain” underlying adult behavior and personality. Furthermore, this system can generate psychiatric morbidity that is not dependent on genetic variation. This view has important ramifications for understanding “pathologies” of human social behavior and cognition as well as providing long‐sought potential mechanistic links between social experience and susceptibility to mental and physical disease.

Relational complexity theory has important virtues, but the present model omits key aspects and evidence. In contrast, skill theory specifies (1) a detailed series of developmental changes in relational complexity from birth to age 30, (2) processes of interaction of content and structure that produce variability in complexity, (3) the role of cortical development, and (4) empirical criteria for complexity levels, including developmental discontinuities. Many findings support these specifications.

This study compared professional and amateur classical musicians matched for age, gender, and education on reaction times during the Stroop color-word test, brainwaves during an auditory ERP task and during paired reaction-time tasks, responses on the Gibbs Sociomoral Reflection questionnaire, and self-reported frequencies of peak experiences. Professional musicians were characterized by: lower color-word interference effects , faster categorization of rare expected stimuli , and a trend for faster processing of rare unexpected stimuli , higher scores on the Sociomoral Reflection questionnaire, (...) and more frequent peak experiences during rest, tasks, and sleep. Both groups had high values on the Brain Integration Scale. These findings are interpreted in light of a Unified Theory of Performance, which posits that effectiveness in any area is influenced by one’s level of mind-brain development—emotional, cognitive, moral, ego and cortical development—with higher mind-brain development supporting greater effectiveness in any domain.

This sequel to the widely read Zen and the Brain continues James Austin's explorations into the key interrelationships between Zen Buddhism and brain research. In Zen-Brain Reflections, Austin, a clinical neurologist, researcher, and Zen practitioner, examines the evolving psychological processes and brain changes associated with the path of long-range meditative training. Austin draws not only on the latest neuroscience research and new neuroimaging studies but also on Zen literature and his personal experience with alternate states of (...) consciousness.Zen-Brain Reflections takes up where the earlier book left off. It addresses such questions as: how do placebos and acupuncture change the brain? Can neuroimaging studies localize the sites where our notions of self arise? How can the latest brain imaging methods monitor meditators more effectively? How do long years of meditative training plus brief enlightened states produce pivotal transformations in the physiology of the brain? In many chapters testable hypotheses suggest ways to correlate normal brain functions and meditative training with the phenomena of extraordinary states of consciousness.After briefly introducing the topic of Zen and describing recent research into meditation, Austin reviews the latest studies on the amygdala, frontotemporal interactions, and paralimbic extensions of the limbic system. He then explores different states of consciousness, both the early superficial absorptions and the later, major "peak experiences." This discussion begins with the states called kensho and satori and includes a fresh analysis of their several different expressions of "oneness." He points beyond the still more advanced states toward that rare ongoing stage of enlightenment that is manifest as "sage wisdom."Finally, with reference to a delayed "moonlight" phase of kensho, Austin envisions novel links between migraines and metaphors, moonlight and mysticism. The Zen perspective on the self and consciousness is an ancient one. Readers will discover how relevant Zen is to the neurosciences, and how each field can illuminate the other. (shrink)

The brain ventricular system is a series of connected cavities, filled with cerebrospinal fluid (CSF), that forms within the vertebrate central nervous system (CNS). The hollow neural tube is a hallmark of the chordate CNS, and a closed neural tube is essential for normal development. Development and function of the ventricular system is examined, emphasizing three interdigitating components that form a functional system: ventricle walls, CSF fluid properties, and activity of CSF constituent factors. The cellular lining of (...) the ventricle both can produce and is responsive to CSF. Fluid properties and conserved CSF components contribute to normal CNS development. Anomalies of the CSF/ventricular system serve as diagnostics and may cause CNS disorders, further highlighting their importance. This review focuses on the evolution and development of the brain ventricular system, associated function, and connected pathologies. It is geared as an introduction for scholars with little background in the field. (shrink)

The development of theories of global cortical dynamics, using linear wave theory, owes much to the pioneering work of Nunez. His work leads to clear predictions on relations of brain size, axonal conduction velocity, and the frequencies of the cerebral rhythms. These predictions do not appear to be fulfilled, but their falsification constrains the range of parameters applicable in further formulations.
