Fig. 5: Visualizing monkey DMFC activity during a timing task.
From: Rastermap: a discovery method for neural population recordings
a, Top: two visual cues were flashed, indicating a ‘ready’ and a ‘set’ signal. The monkey needed to reproduce the time interval between these cues using its own ‘go’ action (saccade or joystick movement). Bottom: short and long trial blocks49. b, PSTHs for neurons sorted by Rastermap. The PSTHs of each neuron were z-scored together across conditions for visualization. c, The difference in neural responses between the top and bottom panels in b corresponding to the same time interval in blocks with different priors. Colored vertical dashed lines denote ready cue time, set cue time and go (action) time that maximizes reward. The color bar shows the difference in z-scored activity. ts, sample interval; tp, production interval.
