The investigation of respiratory differences during different auditory stimuli in schizophrenia patients

Abstract

Here, respiratory signals were recorded from schizophrenia patients and healthy controls. The purpose of this study is to compare the respiratory effects as respiration rate and depth of different auditory stimuli in these two groups. Signals derived from a strain gauge attached to the chest were recorded for 8 min. which includes silence, Classical Turkish Music (CTM) and acoustic white noise stimulation periods. Although CTM, evoked an increase in respiration rate and a decrease in respiration depth in the control group, only a respiration rate acceleration was found in the patient group. Results showed that in order to evaluate the responses of the autonomic system and to clarify the effects of CTM, different physiological measurements taken into account. As a result of this, the emotional changes could be evaluated quantitatively.
