Figure 3.
Single BLA neuron showing an increase in firing rate within seconds after the reinforced response for cocaine, characteristic of type RFe activity. Top, Single-trial raster plot and PEH of BLA cell firing within a 20 sec analysis interval relative to the lever press response. The duration of drug infusion is indicated by the horizontal line below the PEH. Bottom, PEH showing the activity of the same BLA neuron displayed across a longer interval encompassing a large portion of the interinfusion interval. The PEH excludes activity in which lever presses occurred within intervals on either side of the response.
