ABSTRACT
The human psyche is so largely dependent in all its functions on the cerebral cortex and on this alone that it is said to be located there. 2 But not all functions of the cerebral cortex belong to the complex which we ordinarily call psychic. 3 Thus what has been called psychic fluctuations of the vascular tone or of the secretions are cortically directed functions, which though depending on the psyche in some manner are not psychic.
