Temporal lobe neural circuits linked to insomnia in depression

A neuroimaging study has found that people with depression and insomnia have higher resting-state functional connectivity in the superior temporal gyrus region of the brain on both sides. This type of connectivity was decreased in the left supplementary motor area and bilateral postcentral gyrus regions of the brain. The study gives an important contribution to the scientific understanding of neural correlates of insomnia in people with depression.
