The lateral septum (LS) demonstrates activation in response to pup exposure in rat mothers, and its lesions eliminate maternal behaviors suggesting its involvement in maternal brain circuitry. This study shows that the density of pup-activated neurons in the ventral subdivision of the LS (LSv) is nearly equivalent to that in the medial preoptic area (MPOA), the major regulatory site of maternal behavior. When somatosensory inputs including suckling are not allowed, pup-induced activation was markedly reduced in the LSv. Retrograde tract tracing identified various brain regions potentially infl
