Fig. 1: Variation in brain activity across individual trials in Experiment 1.

From: Multiple brain activation patterns for the same perceptual decision-making task

Fig. 1

A In Experiment 1, standard group analyses identified voxels with strong increases and decreases in task-induced brain activation across the cortex. The group brain map is thresholded at P < 0.001 for display purposes. B Brain activation maps for trial 6 and trial 2 from subject 1 demonstrate substantial variability across trials that is not represented in the standard group brain map. Brain maps for the individual trials are thresholded at |beta| > 0.25 for display purposes. Black circles highlight the activation in the posterior cingulate cortex and orbitofrontal cortex. B is shown for illustrative purposes only; formal analyses of the different activation patterns are shown in Figs. 2–8.
