From: Sleepiness induced by sleep-debt enhanced amygdala activity for subliminal signals of fear
Functional connectivity with the amygdala in fear contrasts. The map shows significant functional connectivity between the bilateral amygdala and other voxels in the brain in both the SC and SD sessions. Significant connectivity was found in the cluster including the superior colliculus, peak MNI coordinate (x, y, z) = (−4, −26, −10) mm, t(21) = 5.43, p = 0.0001, k = 26 contiguous voxels. A significant cluster with a significant connection to the amygdala is rendered on a T1 anatomical referential image displayed by neurological convention, with the left side corresponding to the left hemisphere.
