Specific Hypothalamic Neurons Required for Sensing Conspecific Male Cues Relevant to Inter-male Aggression

0

How hypothalamic neurons transduce sex signals emitted by conspecifics to trigger appropriate behavioral outputs remains unclear. Chen et al. identify PMvDAT+ neurons as a key node that extract male-relevant information from the chemosensory pathway, via the v-BNST, to coordinate multiple behavioral responses, including male urine preference, inter-male aggression, and urine marking.
