Figure 7

Neurons inhibited prior to lever press responses exhibit prolonged responses on high cost or delayed reward trials. All conventions follow from Fig. 6. (a-b) PEH and raster plots from a representative response-inhibited NAc neuron on low and high cost trials. (c) Mean (± SEM) Z-score of 58 neurons that were inhibited before the initial response in the effort task. On high cost trials, activity was significantly lower than baseline both following the initial response and prior to reward delivery (*p < 0.01). (d-e) PEH and raster plots from a representative response-inhibited NAc neuron on immediate and delayed reward trials. (f) Mean (± SEM) Z-score of 35 neurons that were inhibited before the lever press response in the delay task. On delayed reward trials, activity was significantly lower than baseline both following the lever press response and prior to reward delivery (*p < 0.01).
