Pharmacological Isolation of Cognitive Components Influencing the Pupillary Light Reflex

Figure 2

Same data as Figure 1, with initial diameters subtracted and scale increased. Note reduction of the light reaction for the Subtract 7 condition in both the placebo and dapiprazole conditions. For the dapiprazole administration, the data for the No Task and Add 1 conditions are nearly identical and are completely superimposed as a single line in the tropicamide condition with No Task condition overlaying the Add 1 data completely.
