Neural circuitry underlying cortical control of a vocalization-driven maternal behavior

Perception of vocalizations is crucial for social behavior. A highly conserved example of this is mothers responding to distress vocalizations from infants. In mice, experienced mothers (dams) find and retrieve isolated pups into the nest when pups emit ultrasonic vocalizations (USVs). This behavior can be learned by virgin females that are co-housed with a dam and litter, and expertise is correlated with plasticity in the left auditory cortex. This plasticity may support learning via top-down projections from cortex to earlier structures in the auditory pathway. The central auditory pathway is highly interconnected, with dense “corticofugal” feedback projections from auditory cortex to earlier structures that may support vocal perception by filtering incoming auditory input. I have examined the contribution of corticofugal projections to perception and retrieval behavior using a combination of in vivo imaging, electrophysiology and circuit manipulation techniques, targeting distinct populations of projection neurons using retrograde viruses. Results from chemogenetic silencing experiments during behavior indicate that projections from left auditory cortex to subcortical targets are crucial for behavior, and that specific projection targets may be preferentially involved. Examination of pup call responses in projections to auditory striatum and auditory midbrain revealed greater modulation in midbrain-projecting neurons, and these neurons exhibited persistently increased activity during repeated bouts of calls. Tracking activity in midbrain-projecting neurons over days of pup retrieval experience revealed a diversity of changes in neuronal and population-level responses to calls, suggesting that plasticity in feedback projections from cortex could drive learning.
