Extended Data Fig. 8: VS TANs display homogeneous responses to cue presentations, as well as correlational spiking activity.
From: Dissociable roles of ventral pallidum neurons in the basal ganglia reinforcement learning network
a, TAN responses to cue events. Each row is the Z-score transformed PSTH of a single neuron to the presentation of cues that signal rewarding, neutral or aversive outcomes. Z-scores are color-coded. Abscissa, time (0 – 2 s), zero is the time of cue onset; ordinate, unit number. Cells are randomly ordered. N = 43 neurons. b, TAN average population responses to cue presentations. Abscissa, time (-0.5 – 2 s). The vertical dashed line at t = 0 indicates the time of cue onset; ordinate, normalized firing rate in Hz. Blue, reward trials; green, neutral trials; red, aversive trials. Shaded regions represent SEMs. N = 43 neurons for each trial type. c, Left: mean cross-correlation histogram of simultaneously recorded pairs of TANs (N = 8 pairs). Abscissa: time, ±1 s around the trigger spike (time = 0); ordinate: normalized firing rate in Hz. Shaded region represents SEM. Right: distribution of TAN signal correlations (N = 453 pairs).
