Abstract

The ubiquitous pathways of positive feedback in the human brain are generally held to be a necessary condition for the phenomenon of conscious sensation. However, no dynamic mechanism, no causal link has been established between the physical brain and its mental attributes, our sensations, thoughts, our consciousness. I suggest that the missing link between the world of neurons and that of mind is to be found in the transformations the brain performs on the coordinates of physical space and time. In particular, the convolution of past, present and future, that characterizes subjective sensations, blurs the distinction between cause and effect, and allows the emergence of a self-generated phenomenon of consciousness.
