Abstract Understanding the long-term effects of stress on brain function is crucial for understanding mechanisms depression. The BALB/c mouse strain has high susceptibility to and thus an effective model repeated social defeat (SDS) mice, however, are not clear. Here, we investigated SDS in male mice over subsequent two weeks. Some defeated immediately exhibited avoidance, whereas anxiety-like behavior was only evident at later periods. Furthermore, segregated into groups based level namely, avoidant nonavoidant mice. characteristic avoidance or nonavoidance each individual fixed In addition, developed a semi-automated method analyzing c-Fos expression investigate effect activity more than weeks after end exposure. Following interaction, reduced several regions compared with control correlation among these areas, exception medial prefrontal cortex (mPFC) central amygdala (CeA), increased suggesting synchrony. Notably, lateral habenula (LHb) different between that from those These observations provide insight activity.

Significance The basal forebrain (BF) is traditionally recognized as a brain structure crucial for arousal, attention, learning, and memory. Here, we discovered causal role of the BF in control prosocial behavior, which fundamental our daily life. We showed mice that somatostatin-expressing inhibitory neurons predominantly target GABA disinhibit dopamine ventral tegmental area thereby increase release nucleus accumbens. This disinhibitory circuitry played an essential promoting social interaction behavior. Our findings identify previously unknown function behavior regulation suggest potential therapeutic deficits commonly observed major neuropsychiatric disorders.
