- 요약How do social interactions change how we experience and approach others? In this dissertation, I approached this question by examining emotional processing of infants during maternal behavior in female mice. Utilizing the observation that pup-naive female mice transition from aversion to attentiveness towards pups after interactions with maternal mice and their litters, we investigated the neural mechanisms that regulate flexible affective processing for maternal behavior. We found that rapid plasticity in central amygdala (CeA) transforms infant aversion into attentiveness after initial pup experience. Specifically, projections from CeA to locus coeruleus (CeA→LC) were strongly activated upon initial pup contact leading to pup aversion. CeA→LC pup responses were reduced with parental experience and down-regulating CeA→LC activity led to less aversion. Oxytocin signaling in central amygdala was required to switch pup aversion to attention, inducing rapid long-term depression of excitatory inputs onto projection neurons. CeA→LC projectors released the stress-related hormone corticotropin-releasing factor (CRF) onto LC neurons, modulating phasic firing to regulate attention. This circuit organization enables local CeA computations of pup valence to be broadcast throughout the brain by the LC central arousal system, leading to appropriate pup-directed behaviors depending on adult state.
