Abstract

A theory is outlined that shifts the presumed locus of mind/brain interaction from the whole brain level to that of single neurons. Neuroanatomical and neurophysiological evidence is offered in support of the existence of single neurons that may individually receive dendritic input of sufficient complexity and diversity to account for the full content of conscious experience, and of an arrangement in which the output of multiple such neurons summate to achieve amplification of the individually emitted messages. An ultramicroscopic extension of the theory is suggested as a way of moving forward on the philosophically difficult aspects of the mind/brain problem
