Cerebral localization and the psi syndrome.
On trying to correlate the psi syndrome with a neural substrate, it is necessary to distinguish between spontaneous, "macropsychological" and experimenta, "micropsychological" incidents of the card-calling type. On comparing telepathic drawings with drawings made by brain-injured patients suffering from optical agnosia, the identical tendency to distortion and disorganization of the target materials can be discerned. It suggests that the telepathic subject is "agnostic" in relation to psi impressions, and that his central processing takes place in the right rather than the left hemisphere. The capricious nature of extrasensory perception (ESP) responses of the card-calling type points to fluctuations in the reticular and limbic midbrain system in warding off the intrusion into awareness are subliminal or irrelevant perceptions from the outside world.
