1st instar larva expressing UAS NpHr-YFP in motor neurons (Gal4 BG380). Halorhodopsin is a chloride pump that hyperpolarizes neurons when activated with yellow light
(580 nm). The yellow dot indicates the administration of yellow light.
Channelrhodopsin in Drosophila motor neurons
3rd instar larvae expressing UAS ChR2 in motor neurons (Gal4 BG380). Channelrhodopsin-2 fluxes cations upon exposure to blue light (470nm). Larvae are exposed to 2
hz blue light stimulus. Note the characteristic excitatory contractions. Blue dot indicates presence of pulsatile stimulus
Drosophila courtship and mating
Courtship and mating of two wild-type flies. The four steps of male courtship include orienting toward female, extending and vibrating its wings, tapping female's abdomen, licking, and mounting.
SynaptopHluorin in Drosophila glomeruli
Multiple glomeruli in antennal lobe respond to pheromone stimulation. A neural activity reporter, synaptopHluorin is expressed in odorant receptor neurons and the fluorescence change is recorded
in a live animal. Yellow dot indicates presence of pheromone stimulus.
