What resolves this contention: Wu et al. treat the MPOA galanin population as a single command-like switch capable of inducing parental behavior and suppressing aggression. Kohl et al. instead argue MPOA-galanin is a heterogeneous population whose discrete projection-defined pools each control different parenting components, undermining a single-population/single-function model. / Optogenetic activation of these neurons in virgin males suppresses inter-male and pup-directed aggression and induces pup grooming. / While the MPOA Gal population is active during all episodes of parental behaviour, individual pools are tuned to characteristic aspects of parenting.
