Dependence of prediction accuracy on selection of regions of interest (ROIs) used to compute the prediction. The IDEA algorithm identifies many regions sorted by decreasing power to discriminate morning vs. evening status. The plot shows the effect of including progressively more ROIs from the sorted list. Predictive accuracy peaked with a single region (right entorhinal cortex) and remained above chance with a second region (left entorhinal cortex).
