Did you ever wonder what makes males and females respond differently to the same stimulus? Sex differences are basic for reproduction, parenting and other social interactions. I work on Drosophila sexually dimorphic behaviours and their underlying neuronal circuity. specifically, I use neurogenetic, physiology and neuroanatomy tools to study how different connectivity patterns between male and female flies enable separate behavioural responses to pheromonal stimuli.
a male Drosophila secretes a low-volatile pheromone, which is picked up by a nearby female.
The female processes pheromonal information via parallel neuronal pathways devoted to either identify or locate the male. Illustration: Elfy Chiang, LMB Visual Aids.
