How Basal Ganglia Outputs Generate Behavior

Figure 2

Opponent outputs during temporal differentiation [36]. (a) Illustration of the behavioral task. A food reward is delivered after the release of the lever, if the press duration exceeds the criterion duration set by the experimenter. (b) Location of the electrode array in the substantia nigra. (c) Perievent raster plots illustrating opponent output from the nigral GABAergic projection neurons. Yellow markers indicate start of lever press. Red markers indicate end of lever press on unrewarded trials. Green markers indicate end of lever press on rewarded trials. The press durations are sorted from shortest to longest.
