Category sensitivity of an example PFC neuron. A, The neuron's average activity (mean ± SEM) in response to all images from the two categories under category scheme A. Insets indicate average responses to each image across the sample presentation and memory delay intervals. B, The same neuron's activity when scheme B was relevant and data were sorted by that scheme. C, The neuron carried less information about category scheme A when the animal was performing category scheme B. sp; Spikes; Fix., fixation epoch.
