CONSCIOUSNESS AND THE BRAIN SELF-REGULATION PARADOX The relationship of consciousness to biology has intrigued mankind thoroughout recorded history. However, little progress has been made not only in understanding these issues but also in raising fundamental questions central to the problem. As Davidson and Davidson note in their introduction, William James suggested, almost a century ago in his Principles of Psychology, that the brain was the organ of mind and be havior. James went so far as to suggest that the remainder (...) of the Principles was but a "footnote" to this central thesis. This volume brings together diverse biobehavioral scientists who are addressing the various aspects of the mindlbrainlbodylbehavior issue. Although some of the authors have previously published together in other volumes, by and large the particular combination of authors and topics selected by the editors makes this volume unique and timely. Unlike the Consciousness and Self-Regulation series (Schwartz & Shapiro, 1976, 1978), also published by Plenum, this volume is devoted entirely to a psychobiological approach to consciousness. Although readers will differ in their interest in specific chapters, the well-rounded investigator who is concerned with the psychobiology of consciousness will want to become intimately acquainted with all the views presented in this volume. As noted by the individual contributors, the topic of this volume stimulates fundamental questions which, on the surface, may appear trivial, yet, on further reflection, turn out to have deep significance.

This book develops a new theory of determinism that offers fresh insights into questions of how intentions and other mental events relate to neural events, how both come about, and how both result in actions. Honderich tests his theory against neuroscience, quantum theory, and possible philosophical refutations, and discusses the consequences of determinism and near-determinism for life-hopes, knowledge, and personal feelings.

The book describes three elementary units of action – the reflex, the oscillator, and the servomechanism – and the principles by which they are combined to make complex units. The combining of elementary units to make complex units gives behavior and the neural circuitry underlying behavior a hierarchical structure. Circuits at higher levels govern the operation of lower circuits by selective potentiation and depotentiation: by regulating the potential for operation in lower circuits – raising the potential for some and lowering (...) it for others – a higher unit establishes the overall pattern to be exhibited in the combined operations of the lower units, while leaving it to the lower units to determine the details of the implementation of this pattern. A theory of motivation of the kind long championed by ethologists and physiological psychologists grows out of the notion of the selective potentiation and depotentiation of hierarchically structured units of behavior. The question then becomes how this conception of motivation may be integrated with a conception of a learned representation of the world to yield a theory of how animals produce novel motivated behavioral sequences based on learned representations. The representation of space, which is central to the behavior of organisms at least as lowly as the digger wasp, is a promising domain for the investigation of this question. Another promising area is the representation of skilled movements, such as handwriting. A number of issues in cognitive and developmental psychology are illumined by this theory about the organization of action. Among these are the degrees-of-freedom problem, the role of practice in development and in the learning of skilled action, and the role of mental rotation of spatial representations. (shrink)

Brain functions are stochastic processes without intentionality whereas mind emerges from brain functions as a Hegelian “change from quantity”, that is, on the order of 1012 profusely interconnected neurons, “into a new quality”: the collective phenomenon of the brain's self-experience. This self-referential and self-observing quality we have in mind is capable of (recursively) observing its self-observations, i.e., interpreting change that is meaningful in relation to itself. The notion of self-interpretation embodies the idea of a “hermeneutic circle”, that is, (in interpretation (...) theory) the treatment of the whole in relation to its parts. (shrink)

I am going to attempt to argue, given certain premises, there are reasons, not only empirical, but also logical, for expecting a certain division of labor in the processing of information by the human brain. This division of labor consists specifically of a functional bifurcation into what may be called, to a first approximation, "verbal" and "nonverbal" modes of information- processing. That this dichotomy is not quite satisfactory, however, will be one of the principal conclusions of this chapter, for I (...) shall attempt to show that metaphor, which in its most common guise is a literary, and hence a fortiori a "verbal" phenomenon, may in fact be more a function of the "nonverbal" than the "verbal" mode. (For alternative attempts to account for cognitive lateralization, see e.g. Bever, 1975; Wickelgren, 1975; Pendse, 1978.). (shrink)

“Real prophecy is always “if... then...” If you commit adultery with your neighbor's wife, then you will roast in hell. But if you love God with all your heart, then you can create the Kingdom of Heaven on earth.”According to the Oxford Dictionary of English Etymology the meanings of ‘divine’ are ‘pertaining to God, godlike, soothsayer and seer’ while ‘to divine’ (after the Latin divinare) is to ‘foretell, predict or make out as by supernatural insight’.

It follows from the temporal nature of mind—the main concern of this essay—that mind functions are not localized in brain space.“ Time is extendedness, probably of the mind itself”, concludes Saint Augustine in Book XI of his Confessions (26.33), and, in our days, this extendedness can be made visible through an oscilloscopic “line” or trace of slow potentials. These graded, additive (not all-or-none) autorhythmic and seemingly self-generating potentials are primary events recorded at synapses. Autorhythmic brain structures (Zabara, 1973) appear to (...) be the source of time frames, while a change in time frames (as reflected in the EEG) leads to synchronization and desynchronization of brain structures respectively. Synchronization forms a homogeneous time domain, such as obtained during rhythmic exercises, chanting, listening to music and mental processes that are the hallmark of religious practices (Rogers, 1973). Desynchronization of brain structures on the other hand marks a functional independence of neuronal elements with each element available for separate channels of data processing, for example, during hallucinogenic drug-induced central sympathetic arousal, that is, a waking dream state (Fischer, 1979).
