Figure 6.
Time-dependent selectivity of each neuron for each of the behavioral factors. For each 200 ms time bin in the task period, properties of individual neurons were classified into one of five categories based on their specific selectivity for each of the behavioral factors. Activity profiles of individual neurons (n = 773) are then displayed consecutively; each row represents data for a single neuron. A, Neurons were sorted according to the selectivity at the end of the instructed-delay period (marked with B) and just after the choice cue onset (marked with C). B, Neurons were sorted according to the selectivity at the end of the instructed-delay period (marked with B) and at the GO signal onset (marked with D). Different colors indicate the selectivity of the neurons for the action plan (blue), choice cue location (gray), action plan and choice cue location (yellow), and motor plan (red). To the right of each panel, the selectivity of each neuron classified at the two 200 ms bins (labeled with B, C or B, D) is indicated. Ap, Activity selective for the action plan; Ch, activity selective for the choice cue location; AC, activity selective for the action plan and choice cue location; Mp, activity selective for the motor plan; ns, nonselective activity.
