The interhemispheric functional connectivity between motor cortices chosen as control ROIs for this analysis show no relationship between spontaneous activity and free recall performance. A) Motor cortex ROIs (shown in yellow) were manually labeled on the approximate hand areas of the left and right precentral gyri. Labels are shown on the semi-inflated cortical surface of the Freesurfer average brain with light gray regions representing gyri and dark grey regions representing sulci. B) The strength of correlation of spontaneous fluctuations in motor cortical activity (z-transformed correlation coefficients, x axis) are plotted against free recall performance (y axis). Strength of correlation between bilateral motor cortical ROIs does not predict episodic memory performance (p = 0.4).
