Sucrose reward suppresses the spontaneous activity of PAM-γ3. (A) Representative images of raw fluorescence of GCaMP expressed in the PAM-γ3 DANs (top), baseline activity (middle), and calcium responses to sucrose stimulation (bottom). (B) Time course of the fluorescence signal. The black bar represents the sucrose presentation. Spontaneous DAN activity is suppressed by the sucrose presentation. (C) Average calcium responses to sucrose presentation. Sucrose intake significantly reduces the activity level of PAM-γ3. Modified from Yamagata et al. (2016).
