The Respiratory Rhythm in Normal and Psychotic Subjects

Abstract

Resp. movements were regular in half of 65 normal individuals, irregular in the others; predominantly regular during the solution of mental problems requiring visual imagery, and tending to be irregular during those requiring auditory imagery; more rapid and shallow in individuals suffering from schizophrenia than in the normal subjects; and regular in a larger % of cases of schizophrenia than in normal subjects. Such patients were subject to periods of unusual irregularities in resp. movements not found in normal subjects, these periods often being associated with hallucinations.
