Social interactions among animals can be complex, and abnormal social behaviours may result in negative fitness consequences for both the individual displaying them, and the entire group. To understand the neural basis of complex social behaviour, we can study simpler behaviours that precede and mediate them. Social spacing, the typical distance between individuals in a group, is an easily quantifiable behaviour in Drosophila melanogaster. Here, I investigated the neural circuitry underlying social spacing through the lens of Autism-candidate gene neuroligin 3. Based on the Nlg3 enrichment pattern in adult fly brains, I hypothesized that nlg3-expressing neurons, along …

Recent studies have linked neuropsychiatric disorders to older parents. These disorders often include changes in social behaviours like the social spacing between neighbouring individuals, which can be modeled in organisms such as Drosophila melanogaster. I investigated the effects of aging on the social space between neighbouring D. melanogaster and how aging impacts the next generation. To achieve this, I used the social space assay and found that individuals become less social with age and that this effect is passed on to the first generation only. Additionally, accelerating the physiological process of aging via increased rearing temperatures or exposure to …
