Figure 3.
A subset of NAc neurons in the core and shell exhibit phasic excitations in cell firing relative to cue onset or the lever press response. a) PEH and raster display show the activity of a representative DSe neuron; activity is aligned to DS-onset (left panel; dotted line) or the lever press response (right panel; dotted lined). DSe epoch (signal period) is denoted by the gray bar. b) Average firing rate across baseline and signal periods for all DSe neurons in the core and shell. c) PEH and raster display show the activity of representative PRe neuron; activity aligned to DS-onset (left panel; dotted line) or the lever press (right panel; dotted lined). PRe epoch (signal period) is denoted by the gray bar. d) Average firing rate during the baseline and signal periods for all PRe neurons in the core and shell. e) PEH and raster display show activity of a representative RFe neuron; firing aligned to DS-onset (left panel; dotted line) or operant response (right panel; dotted lined). RFe epoch (signal period) is denoted by the gray bar. f) Average firing rate during the baseline and signal periods for all RFe neurons in the core and shell. Data and error bars reflect mean ± SEM. * denotes p<0.01.
