Topic: UAS-CsChrimson

The fruit fly Drosophila melanogaster is a model organism in genetics that has contributed significantly to our current understanding of neurology and behavioural biology. Upon optogenetic stimulation of freely moving lilli189Y-Gal4 > UAS-CsChrimson larvae, we observed increased aggregation of larvae compared to wildtype controls. Interestingly, larvae furthermore showed excessive feeding, even if toxic concentrations of additives were present. This culminated in aggressive behaviour where larvae started to devour conspecifics in the absence of other organic media. Stereotyped behavioural o
