This book describes and proposes an unusual integrative approach to human perception that qualifies as both an ecological and a phenomenological approach at the same time. Thomas Natsoulas shows us how our consciousness - in three of six senses of the word that the book identifies - is involved in our activity of perceiving the one and only world that exists, which includes oneself as a proper...

Abstract – IT Lo studio della relazione attore-spettatore può essere oggi approfondita alla luce dei nuovi modelli cognitivi. Questi modelli, legati in diversi modi alle proposte di embodied mind e alla neurofenomenologia introdotta da Varela negli anni ’90, hanno operato tre cambiamenti di paradigma fondamentali per lo studio della relazione teatrale: 1. esiste una connessione diretta tra...

Through dreaming, a different facet of the self is created as a result of a self-organizing process in the brain. Self-organization in biological systems often happens as an answer to an environmental change for which the existing system cannot cope; self-organization creates a system that can cope in the newly changed environment. In dreaming, self-organization serves the function of...

Subjectivity, intentionality, self-awareness and will are major components of consciousness in human beings. Changes in consciousness and its content following different brain processes and malfunction have long been studied. Cognitive sciences assume that brain activities have an infrastructure, but there is also evidence that consciousness itself may change this infrastructure. The two-way...

The transition from wakefulness to sleep represents the most conspicuous change in behavior and the level of consciousness occurring in the healthy brain. It is accompanied by similarly conspicuous changes in neural dynamics, traditionally exemplified by the change from "desynchronized" electroencephalogram activity in wake to globally synchronized slow wave activity of early sleep. However,...

Cognitive neuroscience is the discipline that merges two influential ideas: 1) The mind is an information-processing engine that builds representations of the world and 2) The brain is the locus of all mental activity. Scientists in this field expect to obtain a comprehensive account of our cognitive capacities through the use of imaging techniques such as PET (positron emission tomography) and...

Several lines of evidence converge to the idea that rapid eye movement sleep (REMS) is a good model to foster our understanding of psychosis. Both REMS and psychosis course with internally generated perceptions and lack of rational judgment, which is attributed to a hyperlimbic activity along with hypofrontality. Interestingly, some individuals can become aware of dreaming during REMS, a...

Abstract: Édouard Dujardin's novel Les Lauriers sont coupés (1887) has long been acknowledged as an important influence on the stream of consciousness style (called monologue intérieur by Dujardin) found in James Joyce's Ulysses. Dujardin wrote the book during the period he edited the short-lived Revue wagnérienne. The study shows how monologue intérieur was connected to experimental literary...

Psychosis is one of the cardinal concepts of psychopathology (Jaspers), with an important descriptive use and frequent but unclear nosological connotations. Despite its central role in clinical psychiatry, it is only inadequately and vaguely addressed and articulated in the contemporary psychodiagnostic manuals. Typically, the descriptive use of this concept—as a ”break with reality”—is always...

Color qualia inversion scenarios have played a key role in various philosophical debates. Most notably perhaps, they have figured in skeptical arguments for the fundamental unknowability of other persons’ color experiences. For these arguments to succeed, it must be assumed that a person's having inverted color qualia may go forever unnoticed. This assumption is now generally deemed to be...
