Abstract
An at tempt was made to induce conflict behavior in rabbits by conditioning under hypothalamic electrical stimulation. Behavioral analysis was performed using our newly devised technique which employs the use of a vibration apparatus fixed to head and waist, and a recording of various behavior. Conditioning was carried out by sensory stimuli flight behavior. Reinforcement was as follows : the CS used was flickering light photic (10Hz, 10μsec., ) and acoustic (250Hz, 15 dB) and UCS electrical stimulation (100Hz, 1 msec, , not exceeding 2v) in the medial hypothalamic area and peri-fornix. The restrained animals were placed on a table in an acoustically isolated room with a discrete monotonous back ground noise. CRs were obtained within a short time as were responses: (1) During the autonomicsomatic responses, (2) continuous run and (3) non-continuous run. Data obtained during the non-continuous run represent a conflict-induced type of behavior which may be applied in studies related to the psychopharmacological actions of drugs.
