A. Raster plots of 5 seconds of recording from PERin in 10 different animals, satiated (0H starvation) or food-deprived (24H starvation).
B. Mean firing rate over a 30 second period is not significantly different in satiated (n=6) and food-deprived (n=5) flies by student’s t-test. Individual data points as well as mean ± SEM are shown.
C. Firing rates of PERin neurons before (pre-stimulus) and during stimulation (stimulus) with either 350mM sucrose (left two panels) or 10mM quinine (right two panels) in satiated (0H) and food-deprived (24H) conditions. Pre-stimulus firing rate was averaged over 15 seconds prior to stimulus. Stimlulus duration was 1 second. n=5 flies for each condition, paired t-test. ns.
