Fig. 2: PTTH neurons receive direct input from 5th-LaN, DN1 and DN2 clock neurons.
From: Circuit analysis reveals a neural pathway for light avoidance in Drosophila larvae

a Only one of the PTTH neurons receives input from the 5th-LaN. b, c Both PTTH neurons are postsynaptic to DN1s (b) and DN2s (c). In all panels, presynaptic GFP (cyan), postsynaptic mtdTomato-HA (magenta) and PTTH (green) are shown. Scale bars, 10 μm.
