Supplementary Figure 3: Example single neurons to provide intuition regarding how different task variables are represented at cue 1 presentation.
From: Triple dissociation of attention and decision computations across prefrontal cortex
Each subplot shows a different single neuron example. Bar plots show average firing rate of the neuron to each of the 10 stimuli when presented on left and right of the screen, averaged from 300-500 ms following cue 1 presentation. Line plots show peri-stimulus histograms for each of these conditions, timelocked in ms to cue 1 presentation. (a) Example DLPFC unit reflecting spatial position (high firing for all stimuli on right side of screen. (b) Example OFC unit showing ‘stimulus identity’ coding (esoteric high firing for certain stimuli, replicated on both left/right sides of screen). (c) Example OFC unit showing ‘attended value’ coding (firing linearly scales with value, irrespective of attribute or spatial position). (d) Example ACC unit reflecting action value (high firing for high valued stimuli on left or low valued stimuli on right). (e) Example ACC unit showing ‘accept/reject’ coding (high firing for stimuli ranked 4 or 5; low firing for stimuli ranked 1 or 2).
