Fig. 3: Task-related neural activity changes were regionally widespread and intermixed.
From: Human response times are governed by dual anticipatory processes with distinct neural signatures
A Percentages of electrodes in each region with activity that showed task-related activity changes following S1, S2, or R. Positive values indicate task-related increases in activity; negative values indicate task-related decreases in activity. B Scatterplot showing the relative frequency of electrodes with positive (ordinate) and negative (abscissa) changes in activity to task-relevant events in each intrinsic brain network relative to their overall (expected) frequency across the brain (z-scores). Positive values indicate increased relative frequency; negative values indicate decreased relative frequency. Inner and outer ellipses indicate 1\(\sigma\) and 2\(\sigma\) confidence intervals derived from the joint distribution, respectively. C, D Same as (A, B), but for positive and negative correlations with trial-to-trial, delay-independent RT variability during any time interval. Negative values in (C) indicate increased activity with faster RTs; positive values indicate increased activity with slower RTs.
