Difference in functional connectivity between sleep control (SC) and sleep debt (SD) sessions.

<p>The map shows greater functional connectivity between the left amygdala and other voxels in the brain in SC than SD session. Significant differences were found in the vACC, peak MNI coordinate (<i>x</i>, <i>y</i>, <i>z</i>) = (14, 32, −4) mm, <i>T</i>(13) = 4.77, <i>p</i> = .0001, <i>k</i> = 9 contiguous voxels. The significant cluster with a stronger connection with the left amygdala is rendered on a T1 anatomical referential image displayed in neurological convention, with the left side corresponding to the left hemisphere. The clusters shown are thresholded with a lenient alpha level (<i>p</i><0.01, <i>k</i>>5) for visualization purposes. MNI, Montreal Neurological Institute template; vACC, ventral anterior cingulate cortex.
