Stress-induced brain activation: buffering role of social behavior and neuronal nicotinic receptors.

Abstract excerpt

Social behavior and stress responses both rely on activity in the prefrontal cortex (PFC) and amygdala. We previously reported that acute stress exposure impoverishes social repertoire and triggers behavioral rigidity, and that both effects are modulated by β2-containing nicotinic receptors. We, therefore, hypothesized that the activity of brain regions associated with the integration of social cues will be...
