Abstract:Objective To explore the influence of oxytocin (OT) in the medial amygdala (MeA) on the social behaviors of Brandt's voles (Lasiopodomys brandtii). Methods Oxytocin receptor antagonist (OTRA) was injected into the MeA of male Brants's voles, and then the social behaviors were tested using social recognition experiment and neutral arena encounter experiment. Results The control group (injected with artificial cerebrospinal fluid) took more time to explore the strangers than the familiars (0.001 < P < 0.01). However, the experimental group took the similar time to investigate the strangers and the familiars (P>0.05). And the experimental group spent significantly less time on empty cage, stimulus and strangers than that of the control group (0.01 < P < 0.05). The experimental group showed similar attack time and incubation time of attack than the control (P>0.05). Conclusion OT in MeA can influence the social recognition and memory ability of the Brandt's voles, but cannot affect its attack behavior. Therefore, it was concluded that the expression of OT in MeA could affect Brandt's voles' social behavior by impairing the ability of social memory, rather than changing their prosocial ability.
