Examples of individual NAc neurons showing one of the three types of patterned discharges (PR, RFe and RFi). (a) Example neurons recorded during cocaine self-administration. Raster displays and PEHs show the activity of each neuron recorded during a 20 s time period surrounding the cocaine-reinforced response (indicated by dashed line at time R). Individual cells exhibited type PR activity (left), type RFe activity (middle), or type RFi activity (right). (b) Example neurons recorded during sucrose self-administration.
