This is a unique book. It is excellently written, crammed with information, wise and a pleasure to read.' ---Daniel C. Dennett, Tufts University.

Theories of binding have recently come into the focus of the consciousness debate. In this review, we discuss the potential relevance of temporal binding mechanisms for sensory awareness. Specifically, we suggest that neural synchrony with a precision in the millisecond range may be crucial for conscious processing, and may be involved in arousal, perceptual integration, attentional selection and working memory. Recent evidence from both animal and human studies demonstrates that specific changes in neuronal synchrony occur during all of these processes (...) and that they are distinguished by the emergence of fast oscillations with frequencies in the gamma-range.

Cognitive functions like perception, memory, language, or consciousness are based on highly parallel and distributed information processing by the brain. One of the major unresolved questions is how information can be integrated and how coherent representational states can be established in the distributed neuronal systems subserving these functions. It has been suggested that this so-called ''binding problem'' may be solved in the temporal domain. The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed neurons into (...) cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. As we intend to show here, this temporal binding hypothesis has implications for the search of the neural correlate of consciousness. We review experimental results, mainly obtained in the visual system, which support the notion of temporal binding. In particular, we discuss recent experiments on the neural mechanisms of binocular rivalry which suggest that appropriate synchronization among cortical neurons may be one of the necessary conditions for the buildup of perceptual states and awareness of sensory stimuli.

Sydney Shoemaker notes that my "avoidance of the standard philosophical terminology for discussing such matters" often creates problems for me; philosophers have a hard time figuring out what I am saying and what I am denying. My refusal to play ball with my colleagues is deliberate, of course, since I view the standard philosophical terminology as worse than useless--a major obstacle to progress since it consists of so many errors trapped in the seductively lucid amber of tradition: "obvious truths" that (...) are simply false, broken-backed distinctions, and other cognitive illusions. I want to shift the perspective of philosophy of mind, and for that task using the standard terminology would be counterproductive. Fortunately, the inevitable communication-difficulties my policy provokes are forced into the open by occasions such as this constructive confrontation, permitting me to clarify my shocking message. I am grateful to Shoemaker, and to Michael Tye, Frank Jackson and David Rosenthal, for their vigorous and sympathetic reactions to my book. (shrink)

Hilary Putnam has argued that computational functionalism cannot serve as a foundation for the study of the mind, as every ordinary open physical system implements every finite-state automaton. I argue that Putnam's argument fails, but that it points out the need for a better understanding of the bridge between the theory of computation and the theory of physical systems: the relation of implementation. It also raises questions about the class of automata that can serve as a basis for understanding the (...) mind. I develop an account of implementation, linked to an appropriate class of automata, such that the requirement that a system implement a given automaton places a very strong constraint on the system. This clears the way for computation to play a central role in the analysis of mind. (shrink)

Among psychologists and vision scientists,binocular rivalry has enjoyed sustainedinterest for decades dating back to the 19thcentury. In recent years, however, rivalry''saudience has expanded to includeneuroscientists who envision rivalry as a tool for exploring the neural concomitants ofconscious visual awareness and perceptualorganization. For rivalry''s potential to berealized, workers using this tool need toknow details of this fascinating phenomenon,and providing those details is the purpose ofthis article. After placing rivalry in ahistorical context, I summarize major findingsconcerning the spatial characteristics and thetemporal dynamics (...) of rivalry, discuss two majortheoretical accounts of rivalry ( eye vs stimulus rivalry) and speculate on possibleneural concomitants of binocular rivalry.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

It is argued on the basis of certain mathematical characteristics that classical mechanics is not constitutionally suited to accommodate consciousness, whereas quantum mechanics is. These mathematical characteristics pertain to the nature of the information represented in the state of the brain, and the way this information enters into the dynamics.

Music exists not to be parsed, categorized, or otherwise processed, but because it provides enjoyment. Thus methodologies that concentrate on the cognitive aspects of music alone omit what is essential about this aesthetic form. This paper provides an alternative approach by proposing a measure of musical preference. Specifically, it is argued that a musical passage will be preferred to the extent that it induces synchrony in those brain structures that are responsible for processing the passage. It is first shown that (...) this conception is consistent with time-honored principle of unity in diversity. It is then argued that the synchrony measure follows from more recent results regarding a possible solution to the binding problem. The bulk of the paper, however, is concerned with verifying the measure via simulation. It is shown, in particular, that the measure applied to a network of interacting integrate and fire neurons responsible for the processing of musical stimuli produces results consistent with human musical preference. This was carried out in three areas in the context of Western classical and popular musical forms. First, the model was applied to the laws of voice leading and other principles developed in the period of common harmonic practice. Next, it was shown that the three most salient aspects of melody, the preponderance of stepwise transitions, the theme and variation nature of phrase development, and increased positive affect with exposure all follow directly from the model. Finally, it was demonstrated how a steady rhythm can increase neural synchrony and presumably positive affect. Additional simulations run on Turkish art songs show that the synchrony measure may have some applicability to non-Western musical forms. The paper concludes by arguing that the synchrony measure may, in certain cases, apply to non-musical aesthetic stimuli. (shrink)
