Psychophysiological aspects of regulatory functions in man

The hypothesis on the relationship between biofeedback and the psychophysiological regulatory properties of Ss was tested experimentally. The Ss were 17 adult males after myocardial infarction, 13 patients with bronchial asthma and 18 healthy adults. Biofeedback was followed through a continuous bioelectrical skin reactivity (BSR) recording as an indicator of changes of the activation level and properties of regulatory functions. The data obtained failed to confirm the proposed hypothesis, however, an analysis of BSR as such showed the regulatory functions to follow a different course and have different properties in the experimental and the control groups.
