A circuit logic for sexually shared and dimorphic aggressive behaviors in DrosophilaChiu et al. uncover how a sexually dimorphic behavior is wired in the brains of male and female flies. Looking for neuronal components controlling aggressive behaviors, they find a single type of neuron that controls aggressive approach in both sexes connected hierarchically to different neurons in males versus females that control dimorphic attack responses (lunge versus headbutt, respectively). They then show that social isolation, known to augment aggressive behaviors in both sexes, strengthens the connections between the monomorphic and dimorphic neurons.Chiu et al. uncover how a sexually dimorphic behavior is wired in the brains of male and female flies.
