    A healthcare approach to mental integrity.Abel Wajnerman-Paz, Francisco Aboitiz, Florencia Álamos & Paulina Ramos Vergara - 2024 - Journal of Medical Ethics 50 (10):664-669.
    The current human rights framework can shield people from many of the risks associated with neurotechnological applications. However, it has been argued that we need either to articulate new rights or reconceptualise existing ones in order to prevent some of these risks. In this paper, we would like to address the recent discussion about whether current reconceptualisations of the right to mental integrity identify an ethical dimension that is not covered by existing moral and/or legal rights. The main challenge of (...)

    Voice, gesture and working memory in the emergence of speech.Francisco Aboitiz - 2018 - Interaction Studies. Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies / Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies 19 (1-2):70-85.
    Language and speech depend on a relatively well defined neural circuitry, located predominantly in the left hemisphere. In this article, I discuss the origin of the speech circuit in early humans, as an expansion of an auditory-vocal articulatory network that took place after the last common ancestor with the chimpanzee. I will attempt to converge this perspective with aspects of the Mirror System Hypothesis, particularly those related to the emergence of a meaningful grammar in human communication. Basically, the strengthening of (...)

    (1 other version)The comparative neuroprimatology 2018 road map for research on How the Brain Got Language.Michael A. Arbib, Francisco Aboitiz, Judith M. Burkart, Michael C. Corballis, Gino Coudé, Erin Hecht, Katja Liebal, Masako Myowa-Yamakoshi, James Pustejovsky, Shelby S. Putt, Federico Rossano, Anne E. Russon, P. Thomas Schoenemann, Uwe Seifert, Katerina Semendeferi, Chris Sinha, Dietrich Stout, Virginia Volterra, Sławomir Wacewicz & Benjamin Wilson - 2018 - Interaction Studies 19 (1-2):370-387.
    We present a new road map for research on “How the Brain Got Language” that adopts an EvoDevoSocio perspective and highlights comparative neuroprimatology – the comparative study of brain, behavior and communication in extant monkeys and great apes – as providing a key grounding for hypotheses on the last common ancestor of humans and monkeys and chimpanzees and the processes which guided the evolution LCA-m → LCA-c → protohumans → H. sapiens. Such research constrains and is constrained by analysis of (...)

    Homology: A comparative or a historical concept?Francisco Aboitiz - 1988 - Acta Biotheoretica 37 (1):27-29.
    The meaning of the word homology has changed. From being a comparative concept in pre-Darwinian times, it became a historical concept, strictly signifying a common evolutionary origin for either anatomical structures or genes. This historical understanding of homology is not useful in classification; therefore I propose a return to its pre-Darwinian meaning.

    An interdisciplinary approach to brain evolution: A long due debate.Francisco Aboitiz, Daniver Morales & Juan Montiel - 2003 - Behavioral and Brain Sciences 26 (5):572-576.
    A dorsalization mechanism is a good candidate for the evolutionary origin of the isocortex, producing a radial and tangential expansion of the dorsal pallium (and perhaps other structures that acquired a cortical phenotype). Evidence suggests that a large part of the dorsal ventricular ridge (DVR) of reptiles and birds derives from the embryonic ventral pallium, whereas the isocortex possibly derives mostly from the dorsal pallium. In early mammals, the development of olfactory-hippocampal associative networks may have been pivotal in facilitating the (...)

    Behavior, body types and the irreversibility of evolution.Francisco Aboitiz - 1990 - Acta Biotheoretica 38 (2):91-101.
    A functional approach to evolutionary morphology is emphasized in this paper. This perspective differs from the current structuralist trend, which emphasizes the constraining role of developmental paths. In addition, the present approach agrees with the adaptationist paradigm. It is further argued that three types of phenomena are better understood in this light: i.- the existence of evolutionary trends, ii.- the maintenance of certain structural features within a given taxon, and iii.- the irreversibility of evolution.

    Prelinguistic evolution and motherese: A hypothesis on the neural substrates.Francisco Aboitiz & Carolina G. Schröter - 2004 - Behavioral and Brain Sciences 27 (4):503-504.
    In early hominins, there possibly was high selective pressure for the development of reciprocal mother and child vocalizations such as proposed by Falk. In this context, temporoparietal-prefrontal networks that participate in tasks such as working memory and imitation may have been strongly selected for. These networks may have become the precursors of the future language areas of the human brain.

    The evolutionary origin of the mammalian isocortex: Towards an integrated developmental and functional approach.Francisco Aboitiz, Daniver Morales & Juan Montiel - 2003 - Behavioral and Brain Sciences 26 (5):535-552.
    The isocortex is a distinctive feature of mammalian brains, which has no clear counterpart in the cerebral hemispheres of other amniotes. This paper speculates on the evolutionary processes giving rise to the isocortex. As a first step, we intend to identify what structure may be ancestral to the isocortex in the reptilian brain. Then, it is necessary to account for the transformations (developmental, connectional, and functional) of this ancestral structure, which resulted in the origin of the isocortex. One long-held perspective (...)

    The mesencephalon as a source of preattentive consciousness.Francisco Aboitiz, Javier López-Calderón & Vladimir López - 2007 - Behavioral and Brain Sciences 30 (1):81-82.
    By themselves, mesencephalic subcortical mechanisms provide a preattentive kind of consciousness, related to stimulus-related, short-latency dopamine release triggered by collicular input. Elaborate forms of consciousness, containing identifiable objects (visual, auditory, tactile, or chemical), imply longer-lasting phenomena that depend on the activation of prosencephalic networks. Nevertheless, the maintenance of these higher-level networks strongly depends on long-lasting mesencephalic dopamine release. (Published Online May 1 2007).

    To normalize or not to normalize for overall size?Francisco Aboitiz - 1998 - Behavioral and Brain Sciences 21 (3):327-328.
    I discuss Fitch & Denenberg's argument that no correction for brain size is needed when assessing callosal size. Morphometric criteria may not be sufficient to determine whether corrections are needed. Functional studies of callosal transfer will ultimately specify whether corrections for size are necessary in each case.

    What determines evolutionary brain growth?Francisco Aboitiz - 2001 - Behavioral and Brain Sciences 24 (2):278-279.
    Finlay et al. address the importance of developmental constraints in brain size evolution. I discuss some aspects of this view such as the relation of brain size with processing capacity. In particular, I argue that in human evolution there must have been specific selection for increased processing capacity, and as a consequence for increased brain size.

  13. Schizophrenia is a disease of general connectivity more than a specifically “social brain” network.Conrado Bosman, Enzo Brunetti & Francisco Aboitiz - 2004 - Behavioral and Brain Sciences 27 (6):856-856.
    Dysfunctions of the neural circuits that implement social behavior are necessary but not a sufficient condition to develop schizophrenia. We propose that schizophrenia represents a disease of general connectivity that impairs not only the “social brain” networks, but also different neural circuits related with higher cognitive and perceptual functions. We discuss possible mechanisms and evolutionary considerations.

    Sharpening occam's razor: Is there need for a hand-signing stage prior to vocal communication?Conrado Bosman, Vladimir López & Francisco Aboitiz - 2005 - Behavioral and Brain Sciences 28 (2):128-129.
    We commend Arbib for his original proposal that a mirror neuron system may have participated in language origins. However, in our view he proposes a complex evolutionary scenario that could be more parsimonious. We see no necessity to propose a hand-based signing stage as ancestral to vocal communication. The prefrontal system involved in human speech may have its precursors in the monkey's inferior frontal cortical domain, which is responsive to vocalizations and is related to laryngeal control.

    Frontal and executive dysfunction is a central aspect of ADHD.Ximena Carrasco, Vladimir López & Francisco Aboitiz - 2005 - Behavioral and Brain Sciences 28 (3):427-428.
    In the target article, Sagvolden and collaborators propose that attentional-deficit/hyperactivity disorder (ADHD) is the result of a general behavioral deficit which is mainly caused by a hypofunctioning mesolimbic dopaminergic system. Although we partly agree with this view, we think that it tends to overlook the dysfunction of prefrontal and frontostriatal executive functions by considering them to be a consequence of alterations in reward and extinction mechanisms. Rather, we believe that ADHD is the result of an overall cognitive and behavioral condition, (...)

    What is so informative about information?Carlos M. Hamame, Diego Cosmelli & Francisco Aboitiz - 2007 - Behavioral and Brain Sciences 30 (4):371-372.
    Understanding evolution beyond a gene-centered vision is a fertile ground for new questions and approaches. However, in this systemic perspective, we take issue with the necessity of the concept of information. Through the example of brain and language evolution, we propose the autonomous systems theory as a more biologically relevant framework for the evolutionary perspective offered by Jablonka & Lamb (J&L).

    Faces and Voices Processing in Human and Primate Brains: Rhythmic and Multimodal Mechanisms Underlying the Evolution and Development of Speech.Maëva Michon, José Zamorano-Abramson & Francisco Aboitiz - 2022 - Frontiers in Psychology 13.
    While influential works since the 1970s have widely assumed that imitation is an innate skill in both human and non-human primate neonates, recent empirical studies and meta-analyses have challenged this view, indicating other forms of reward-based learning as relevant factors in the development of social behavior. The visual input translation into matching motor output that underlies imitation abilities instead seems to develop along with social interactions and sensorimotor experience during infancy and childhood. Recently, a new visual stream has been identified (...)
