Consciousness is defined and a relation is established between its altered states of consciousness (ASC) and as well to the ways how they are provoked. Phenomenology of ASC is described and related to psychopathology. A short commentary is made about ASC used in some ethnopsychotherapy. Psychotherapy, of western origin, using ASC, specially hypnosis, directed day-dream (reve eleille dirige) of...

Seth develops a convincing and detailed internalist alternative to the sensorimotor-contingency theory of perceptual phenomenology. However, there are remaining conceptual problems due to a semantic ambiguity in the notion of "presence" and the idea of "subjective veridicality." The current model should be integrated with the earlier idea that experiential "realness" and "mind-independence" are...

Abstract In this essay, I examine conceptual metaphors of the camera eye as figurations of the cinematic dispositif that reflect on sensory and symbolic aspects of cinema. Since camera-eye metaphors often hypothesize between medial, formal and experiential dimensions of film, they are particularly insightful for studying embodied conceptualizations of cinema. Drawing on insights from...

This cross-cultural study compared explanations of sleep paralysis (SP) in two countries and two groups with different levels of education in one country. Comparisons were made between individuals having experienced SP at least once in a lifetime from Cairo, Egypt (n = 89), Copenhagen, Denmark (n = 59), and the American University in Cairo, Egypt (n = 44). As hypothesized, participants from the...

Humor associated mirthful laughter (HAML) similar to meditation, both positive brain states, have complex mental processes that can modulate emotions, cognition, memory, sensory perception, consciousness, hormones, immune, and CNS activity. Meditation is used as a non‐pharmacological lifestyle intervention to provide health benefits, from promoting wellness to alleviating symptoms of a variety...

Neurophysiological and neuroimaging studies including both patients with disorders of consciousness and healthy subjects with modified states of consciousness suggest a crucial role of the medial posteroparietal cortex in conscious information processing. However no direct neuropsychological evidence supports this hypothesis and studies including patients with restricted lesions of this brain...

Addiction theories posit that drug-related cues maintain and contribute to drug use and relapse. Indeed, our recent study in cocaine-dependent patients demonstrated that subliminally presented cocaine-related stimuli activate reward neurocircuitry without being consciously perceived. Activation of reward neurocircuitry may provoke craving and perhaps prime an individual for subsequent...

A widely held view on consciousness is that it is related to the 'broadcasting' of sensory information to the whole brain [1-3]. Despite the fact that there is general support for this view, it remains unclear how exactly this broadcasting is established. It has been proposed [2,3] that thalamocortical circuits are an important mediator of such broadcasting, but empirical support for this claim...

Understanding consciousness is a major scientific challenge of our times, and perceptual awareness is an integral part of that challenge. This Theme Issue aims to provide a timely focus on crucial insights from leading scientists on perceptual awareness and its neural basis. The issue refers to key research questions and findings in perceptual awareness research and aims to be a catalyst for...

This essay critically examines the extent to which binocular rivalry can provide important clues about the neural correlates of conscious visual perception. Our ideas are presented within the framework of four questions about the use of rivalry for this purpose: (i) what constitutes an adequate comparison condition for gauging rivalry's impact on awareness, (ii) how can one distinguish...
