[Modulation of emotional reactions via biocontrolled readjustment of intercentral relations].

In cats, changes in the feedback between the strength of current used for hypothalamic stimulation and the theta--rhythm of temporal cortex exert diverse effects on conditioned response of fear evolved by means of combining an auditory stimulus with electrical stimulation of the same hypothalamic area. Biocontrolled micropolarizattion (BMP) with positive feedback suppresses, whereas BMP with negative feedback enhances the conditioned response. The changes in the feedback during BMP between excitation of temporal cortex and the hypothalamus seem to be a modulation of connections between the centers of conditioned and unconditioned stimuli.
