| Abstract: | An attempt 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 (10 Hz, 10 musec.,) and acoustic (250 Hz, 15 dB) and UCS electrical stimulation (100 Hz, 1 msec., not exceeding 2 v) 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 background 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. |
