Figure 5. Single Neurons Carrying Task-Relevant Information Synchronize to the Currently Relevant Ensemble.

Neurons encoding task-relevant information were more synchronized with the rule-selective ensemble preferring the current rule. Phase locking of stimulus-selective neurons (A) and rule-selective neurons (B) to electrodes that participated in either the color-preferring ensemble (pink) or the orientation-preferring ensemble (purple). Only electrodes that were exclusive to either ensemble were used (i.e., those electrodes participating in both ensembles were excluded). Phase locking is shown for both orientation trials (left) and color trials (right). Shaded regions indicate 95% confidence intervals. Significant differences in phase locking between the two ensembles are indicated at each frequency tested (*p < 0.05; **p < 0.01).
