Activity of a single PFC (A) and ITC (B) neuron during the test epoch. Neuronal activity is grouped according to the category of the test stimulus and whether the category of the test stimulus matched the category of the sample. A, A PFC neuron that showed a match/non-match effect; it responded preferentially to when the test stimulus did not match the sample category. B, An example of a category-sensitive ITC neuron that showed more activity to both the sample and test stimuli when they were dogs as opposed to cats.
