Line Plot from Scientific Research

Top, raster plots of PPL1-DAN spiking on trials when flies received either an individual 200-ms electric-shock pulse (a; 36 trials; 12 flies per cell type, 3 trials per fly, spaced 1.8 s apart) or sucrose for 5 s (b; 10 flies per cell-type, 1 trial per fly). Dashed lines indicate the onset of shock or sucrose availability; grey shading shows periods of shock or feeding. Bottom, trial-averaged mean spike rates (colour shading, s.e.m.).
