The effect of small doses of vasopressin (30 mU/kg) and oxytocin (30 mU/kg) was studied on active and passive avoidance behaviour and exploratory activity. Neither vasopressin nor oxytocin had any effect on acquisition of active avoidance behaviour, while extinction was delayed after vasopressin and facilitated after oxytocin treatment. In passive shock avoidance response (PSAR), vasopressin treatment shortened the PSAR in repeated tests. Oxytocin was ineffective on PSAR. In open field test, only the defecation rate was significantly lowered by vasopressin. (Journal received: Jan. 1977)
