OBJECTIVE In the past decade, much has been written about 'the hard problem' of consciousness in the philosophy of mind. However, a separate hard problem faces the scientific study of consciousness. The problem arises when distinguishing the neural correlates of consciousness (NCC) and the neural constitution of consciousness. Here, I explain this correlation/constitution distinction and the pr...

Scientific studies of consciousness rely on objects whose existence is assumed to be independent any consciousness. On the contrary, we assume fundamental, and that one main features characterized as being other-dependent. We set up a framework which naturally subsumes this feature by defining compact closed category where morphisms represent conscious processes. These are composition generator...

Despite many efforts, there are no computational models of consciousness that can be used to design conscious intelligent machines. This is mainly attributed to available definitions of consciousness being human centered, vague, and incomplete. Through a biological analysis of consciousness and concept of machine intelligence, we propose a physical definition of consciousness with the hope to m...

There are two concepts of consciousness, access consciousness and phenomenal consciousness. But just as the concepts of water and H2O are different concepts of the same thing, so the two concepts of consciousness might come to the same thing in the brain. Some recent papers by Crick and Koch raise issues that suggest that these two concepts of consciousness might have different (though overlapp...

Work on consciousness by neurophilosophers often leaves a certain group of other philosophers frustrated. The latter group of philosophers, which includes people such as believe that consciousness is something quite different from the brain circuitry or other processes that are active in cognition. They feel frustrated because work on consciousness by neurophilosophers usually ignore this view,...

THE mechanism by which general anesthetics prevent consciousness remains unknown largely because the mechanism by which brain physiology produces consciousness is unexplained. But the two mysteries seem to share a critical feature—both consciousness and actions of anesthetic gases are mediated through extremely weak London forces (a type of van der Waals force) acting in hydrophobic pockets wit...
