The quest to understand consciousness, once the purview of philosophers and theologians, is now actively pursued by scientists of many stripes. This paper studies consciousness from the perspective of theoretical computer science. It formalizes the Global Workspace Theory (GWT) originated by cognitive neuroscientist Bernard Baars and further developed by him, Stanislas Dehaene, and others. Our...
BACKGROUND Integrative mental health care can be used to treat depression with a person-centered, lifestyle-modifying, and more salutogenic approach to mental health and human flourishing. In this article, we report on the feasibility and acceptability of a new mind-body program, Meditation Based Lifestyle Modification (MBLM), in outpatients with mild or moderate depression. METHODS This is a...
Current theories of the mind hold that it is physical in nature; however, much debate exists about whether the mind can be interpreted with brain imaging research. The purpose of this paper is to provide a review of theories of the mind and how they relate to current debates on disorders of consciousness, and to explore the ethical implications of medical diagnoses and misdiagnoses. Questions...
ABSTRACT We are conscious beings: Somehow, the activity of our brains and nervous systems gives rise to states in which we have subjective experiences; and when we are in such states, we are aware of specific content. Researchers are only beginning to develop an understanding of the neural mechanisms underlying these phenomena. Much of the research in the last few decades has focussed on...
The promise that Psychedelic Medicine holds for debilitating, treatment-resistant, disorders rests as much upon novel explanations of illness as it does upon novel treatments. If actu-alized, Psychedelic Medicine will revolutionize heath care and theories of healing. Psychedelic medicine ’ s unintended consequences may prove to be just as far-reaching, as non-ordinary states of consciousness,...
The study of unconscious processing requires a measure of conscious awareness. Awareness measures can be either subjective (based on participant’s report) or objective (based on perceptual performance). The preferred awareness measure depends on the theoretical position about consciousness, and may influence conclusions about the extent of unconscious processing and about the neural correlates...

A powerful paradigm to identify neural correlates of consciousness is binocular rivalry, wherein a constant visual stimulus evokes a varying conscious percept. It has recently been suggested that activity modulations observed during rivalry may represent the act of report rather than the conscious percept itself. Here, we performed single-unit recordings from face patches in macaque...
OBJECTIVE: -that emerges from sleep research and theoretical neurobiology-can be applied to pathophysiology and psychopathology in psychiatry. METHODS: Our starting point is that the mind and brain are emergent aspects of the same (neuronal) dynamics; namely, the brain-mind. Our endpoint is that synaptic dysconnection syndromes inherit the same dual aspect; namely, aberrant inference or belief...
Being conscious is a profound aspect of human existence, and understanding its function and its inception is considered one of the truly grand scientific challenges. However, the nature of consciousness remains enigmatic, to a large part because “being conscious” can refer to both the content (phenomenology) and the level (arousal) of consciousness, and how these different aspects are related...
Attention Schema Theory (AST) is a recent proposal to provide a scientific explanation for the basis of subjective awareness. In AST, the brain constructs a representation of attention taking place in its own (and others') mind (`the attention schema'). Moreover, this representation is incomplete for efficiency reasons. This inherent incompleteness of the attention schema results in the...
