sejunction hypothesis
   The term sejunction comes from the Latin noun seiunctio, which means divorce, separation. It was introduced in or shortly before 1900 by the German neurologist Carl Wernicke (1848-1904) to denote an intracerebral mechanism by means of which regular associative processes are blocked and then shunted into an aberrant direction. In conformity with the *dissociation model of hallucinatory experience as formulated by the German hallucinations researcher Edmund Parish (18611916), Wernicke's sejunction hypothesis postulates that the majority of hallucinatory phenomena arise from aberrant activation of the sensory cortex's projection fields, in the absence of a matching object or stimulus in the outside world.
