Fig. 5: Subspecialization of P1 neuron subtypes.
From: A modular circuit coordinates the diversification of courtship strategies
a,b, Diagrams summarizing proposed sensory specializations of Fru∩P1 and Dsx∩P1 in D. melanogaster (a) and D. yakuba (b). Pheromone inputs inferred from functional imaging and behavioural data in Fig. 4 and Extended Data Fig. 6 or previously reported13,19,24,25 are indicated by solid arrows. Further hypothesized sensory inputs are indicated by dotted arrows. c, Model for the diversification of courtship behaviours by neural subspecialization. Independent retuning of sensory inputs to behaviourally redundant but molecularly distinct P1 subtypes may facilitate the rapid evolution of sensory signals that control a male’s sexual arousal and courtship.
