Serotonin is a small molecule that regulates many functions in the brain including the formation of neural circuits. Our lab is interested in both how serotonin functions and how to examine neural circuits.
Larval vision paper in press Nature Comm; this paper presents evidence that larvae can 'see' other larvae.
Check out this video; it shows a larva circling under tethered target larvae. However, the target larvae are on the other side of the petri dish plastic indicating that vision is the primary means of detection.
Most of the larval interneurons traced. See below for 55 GAL4 traced interneurons
