I am thrilled to share our latest work: we identified a population of central amygdala neurons that promote the earliest and perhaps most important social behavior: pup suckling!... We also developed new tools for pup neuroscience

Mothers can fiercely defend their young, but how the brain triggers this response remains to a large extent a mystery. Here, authors show that a dormant, hormone-sensitive brain circuit switches on to spark maternal aggression during the lactation period.
