Vectorial Cerebral Hemisphericity as Differential Sources for the Sensed Presence, Mystical Experiences and Religious Conversions
Perceptual and Motor Skills June 1, 1993 M. A. Persinger 86 citations
Multiple variants of the sensed presence often precede mystical and religious experiences, which are frequently followed by sudden, permanent changes in self-concept. The model of vectorial hemisphericity proposes that the relative metabolic activity of synaptic patterns between the cerebral hemispheres during transient interhemispheric intercalation determines the affect, content, and type of experience. Depending on the relative activity of the two hemispheres, intrusions of the right hemispheric equivalent of the left hemispheric sense of self generate experimental phenomena including "evil entities," gods, out-of-body experiences, and alterations in space-time. Conditions that facilitate interhemispheric intercalation and the generation of these experiences are discussed.
