Figure 5.

Precue single-unit activity. ACC (A–C, top) and mPFC (D–F, bottom). A, Histograms aligned to cue onset (arrow) are shown from an example excitatory unit (top) and an example inhibitory unit (bottom). The unit's phasic response before the cue on correct trials (red) and the activity of the same unit on incorrect trials (green) and omission trials (blue). B, The percentage of total units which responded before the cue on correct trials (red), incorrect trials (green), and omission trials (blue). Excitatory units are shown as solid bars, and inhibitory units are shown as hashed bars. C, The population activity (excitatory, solid line; inhibitory, dashed line) of precue responsive units on correct trials and the activity of those same units on incorrect and omission trials. The lines represent the mean activity and the shaded areas represent the SE. D–F, PFC, same as above.
