ニューロン発火がなぜ「心」になるのか? 私が私であることの不思議、意識の謎に正面から挑んだ、茂木健一郎の核心!

_In what computational aspect is the brain different from the_ _computer? In what objective measures can the brain said to be_ _“creative”? These are the fundamental questions that concerns the_ _neural basis of human mental activity. Here we discuss several_ _important aspects of the essential computational ingredients of human_ _mind in order to understand the “creative” process going on in the_ _brain. One of the key concepts is the nature of the source of_ _"externality" that adds new ingredients to the (...) system and its output. We_ _argue that in addition to information input and stochasticity, we need to_ _consider a third possibility, namely "dynamics-embedded externality"._ _We discuss how the neural origin of the subjective sensory qualities_ _ is related to this aspect of creativity. The invariance of qualia _ _under a certain class of transformation, and the mapping of discrete,_. (shrink)

_The concept of qualia describes the unique properties that_ _accompany our senses. It is an essential concept when we try to_ _understand the principle that bridges the neural firings in our_ _brain and our perception. The idea of qualia is also of crucial_ _importance when we try to study the functions of the brain from_ _an objective point of view. Qualia must be part of the_ _mathematical formulation of information we use to understand_ _the function of the brain._.

manner. The construction of the space-time structure that describes the dynamics of the neural network in a causal manner is a non-trivial problem. I critically review the idea of response selectivity as is applied to.

The privileged position of neural activity in biological neuroscience might be justified on the grounds of the nonlinear and all-or-none character of neural firing. To justify the neuron doctrine in cognitive neuroscience and make it both plausible and radical, we must consider the supervenience of elementary mental properties such as qualia on neural activity.

We analyzed the variability of response in records obtained from MT (V5) of awake, behaving monkeys and kindly provided to us by Newsome and Bair (see Newsome et al 1990 for Methods). Some sets of random dot kinematograms had been generated with a constant randomization seed (novar stimuli), while others had been generated with varying randomization seeds (var stimuli). The neural responses to novar stimuli exhibited a remarkable degree of consistent temporal modulation, while the responses to var stimuli were homogeneous (...) over the presentation time. We suspected that correspondence noise might be a major source of variability and to test this we compared the variability of response to novar and var stimuli, making the assumption that the variability observed in responses to novar stimuli reflected the internal noise only, whereas variability in the case of var stimuli reflected internal noise and external noise. From this assumption, we could estimate the relative importance of external noise and internal noise in this system. The main conclusions are:- (1) Efficiency values (up to about 35%) calculated from neural responses in MT are of the same order as those of human observers, (Barlow and Tripathy 1997) (2) External correspondence noise is a significant factor in limiting the detectability of coherent motion in these random dot stimuli.

Although far from unanimous, there seems to be a general consensus that neither mind nor brain can be reduced without remainder to the other. This essay argues that indeed both mind and brain need to be included in a nonreductionistic way in any genuinely integral theory of consciousness. In order to facilitate such integration, this essay presents the results of an extensive cross-cultural literature search on the ‘mind’ side of the equation, suggesting that the mental phenomena that need to be (...) considered in any integral theory include developmental levels or waves of consciousness, developmental lines or streams of consciousness, states of consciousness, and the self . A ‘master template’ of these various phenomena, culled from over one-hundred psychological systems East and West, is presented. It is suggested that this master template represents a general summary of the ‘mind’ side of the brain-mind integration. The essay concludes with reflections on the ‘hard problem', or how the mind-side can be integrated with the brain-side to result a more integral theory of consciousness. (shrink)

David Brink has recently argued for the “parity” of ethics and the sciences. While the parity claim alone might be metaphysically neutral, Brink favours a form of ethical naturalism on which moral properties “are” natural properties, just as non-moral macrophysical properties “are” the microphysical states that compose them. Brink supports this claim by showing that both types of properties share certain important features: specifically, that both may be constituted, supervening and synthetically necessitated. I shall argue that notwithstanding these common features, (...) there remain significant modal differences in the way the two types of properties are assigned to the world. These differences represent an important respect in which moral properties are not on par with their scientific counterparts. (shrink)

"Childhood Spirituality," "The Hidden Message of Descartes," "Boomeritis Buddhism," "Sharing and Caring," and "The Meaning of 'Levels' of Consciousness." Please stay tuned!

"Oh really. The Cartesian dualism is the major sin of modernity, didn't you know that?" She began laughing, as if this were some sort of inside joke. "And you don't want to be living in sin, do you? What are you, Wilber, all of 20 years old? And already living in sin.".

The last positive statement I made about Da's work was in 1985, when I wrote a very strong endorsement for his major book, The Dawn Horse Testament. This is one of the very greatest spiritual treatises, comparable in scope and depth to any of the truly classic religious texts. I still believe that, and I challenge anybody to argue that specific assessment.

For many years—actually, for about 3 decades—I have respectfully declined any sort of in-depth interview about my work, simply because I did not want my person to be the point; I wanted the ideas themselves to be the point, and so I have kept a very low public profile (as I'm sure I don't have to tell most of you).

Le concept de «Stellvertretung» – traduit en français habituellement par «substitution» ou «représentation» – intéresse de nombreux théologiens germanophones qui cherchent à rendre compte de la signification de la mort du Christ sur la croix. L’article met en valeur la caractéristique de ce concept d’abord en fonction des deux moments, qui en sont constitutifs, d’«inclusion» et d’«exclusion», puis en contraste avec deux concepts voisins, ceux de «remplacement» et de «solidarité». Il montre que l’acte de celui qui est mort et ressuscité (...) est double: il ne prend pas simplement la place du pécheur mais il lui fait une place, celle du justifié. L’article aborde enfin l’Apocalypse de Jean afin d’y vérifier la pertinence de cette catégorie de «prendre-et-faire place» du Christ, fondée sur l’acte intratrinitaire de Dieu le Père qui fait place à son Fils.

We propose a new dynamical mechanism for information processing in mind and brain. We emphasize that a hermeneutic process is one of the key processes manifesting the functions of the brain and that it can be formulated as an itinerant motion in ultrahigh dimensional dynamical systems, which may give a new realm of the dynamic information processing. Our discussions are based on the notion of chaotic information processing and the observations of biological chaos.

Nietzsche famously rails against Christian virtues such as humility and compassion. Yet he is well aware that historical Christians, especially those in positions of power, typically preached such values but did not practice them. This raises the question whom Nietzsche is really targeting in his animadversions against Christian virtues. The answer developed here is that his real targets are his contemporaries, including atheist, socialists such as Eugen Dühring, who, with their advocacy of egalitarian, democratic social and political policies, are trying (...) to implement the values Christians long preached but rarely practiced. In nominating moderns, including those who seek the realization of enlightenment liberal democratic values, rather than past Christians, as Nietzsche’s real targets we create space for reconciling Nietzsche’s claim that he accepts the past (as embodied in his doctrine of amor fati) with his project of seeking to open up new possibilities for the future. In the concluding sections the questions are raised to what extent do Nietzsche’s attacks on Christian virtues exhibit the very ressentiment he so vehemently criticises as a source of Christian values, and whether his criticism of the modern social and political implementation of those values is really supported by his own values.

Using the concepts of chaotic dynamical systems, we present an interpretation of dynamic neural activity found in cortical and subcortical areas. The discovery of chaotic itinerancy in high-dimensional dynamical systems with and without a noise term has motivated a new interpretation of this dynamic neural activity, cast in terms of the high-dimensional transitory dynamics among “exotic” attractors. This interpretation is quite different from the conventional one, cast in terms of simple behavior on low-dimensional attractors. Skarda and Freeman (1987) presented evidence (...) in support of the conclusion that animals cannot memorize odor without chaotic activity of neuron populations. Following their work, we study the role of chaotic dynamics in biological information processing, perception, and memory. We propose a new coding scheme of information in chaos-driven contracting systems we refer to as Cantor coding. Since these systems are found in the hippocampal formation and also in the olfactory system, the proposed coding scheme should be of biological significance. Based on these intensive studies, a hypothesis regarding the formation of episodic memory is given. Key Words: Cantor coding; chaotic itinerancy; dynamic aspects of the brain; dynamic associative memory; episodic memory; high-dimensional dynamical systems; SCND attractors. (shrink)

Ken Elkins retired as chief photographer of the Anniston Star in 2000, and this selection of his work demonstrates his brilliant eye for finding and capturing images of rural southern lives and landscapes in all their difficulty, candor, and humor. These are unadorned images of a timeless landscape and proud resourceful people, who know well their neighbors, honor their past, and face the tests of daily life with wit and a stoic sense of endurance.

Biological understanding of human cognitive functions is incomplete because of failure to understand the evolution of complex functions and organisms in general. Here, that failure is attributed to an aspect of the standard neo-Darwinian synthesis, namely commitment to evolution by natural selection of genetic programs in stable environments, a position that cannot easily explain the evolution of complexity. When we turn to consider more realistic, highly changeable environments, however, another possibility becomes clearer. An alternative to genetic programs—dubbed “biogrammars”—is proposed here (...) to deal with complex, changing environments and explain evolving complexity from pre-genetic life to human socio-cognitive functions.

This paper presents, from the perspectives of both social scientists and microbiologists, a case study of the implementation and practice of Responsible Innovation (RI) in a UK-based synthetic biology project. We highlight the impact of interdisciplinary working and examine the benefits that arise from creating the time and space for shared reflection on research. Our discussions over the course of the project included concerns about the potential escape to the environment of laboratory-constructed genetic material and alternatives to the role that (...) antibiotic resistance genes play in synthetic biology. As a result, the design of a key product of the project was altered in ways that go beyond normal institutional requirements. We highlight our view of the importance of continued interdisciplinary collaboration and the utility of the framework of Responsible Innovation in achieving this. We conclude with observations on the difficulties of sustaining such collaborations. (shrink)

Many philosophy majors are shocked by the gap between the relative ease of lower-level philosophy courses and the difficulty of upper-division courses. This book serves as a necessary bridge to upper-level study in philosophy by offering rigorous but concise and accessible accounts of basic concepts and distinctions that are used throughout the discipline. It serves as a valuable advanced introduction to any undergraduate who is moving into upper-level courses in philosophy. While lower-level introductions to philosophy usually deal with popular topics (...) accessible to the general student in a piecemeal fashion, The Philosophy Major's Introduction to Philosophy offers coverage of important general philosophical concepts, tools, and devices that may be used for a long time to come in various philosophical areas. The volume is helpfully divided between a focus on the relation between language and the world in the first three chapters and coverage of mental content in the final two chapters, but builds a coherent narrative from start to finish. It also provides ample study questions and helpful sign-posts throughout, making it a must-have for any student attempting to engage fully with the problems and arguments in philosophy. Key Features Integrates topics from various areas of philosophy, such as philosophy of language, metaphysics, epistemology, ethics, and philosophical logic Provides descriptions of logico-mathematical tools necessary for philosophical studies, such as propositional logic, predicate logic, modal logic, set theory, mereology, and mathematical functions Makes connections with modern philosophy, including discussions of Descartes's skepticism and dualism, Locke's theory of personal identity, Hume's theory of causation, and Kant's synthetic a priori. Includes well-known entertaining puzzles and thought experiments such as the Ship of Theseus, the Statue and the Clay, a Brain in a Vat, and Twin Earth Lists helpful Exercise Questions and Discussion Questions at the end of each chapter and answers selected questions at the back of the book.
