Low white-matter integrity between the left thalamus and inferior frontal gyrus in patients with insomnia disorder

Abstract

The insomnia group showed decreased integrity in the left thalamus–pars triangularis tracts, and integrity was correlated with cognition and daytime sleepiness. These results may imply that insomnia is characterized by disintegration of the white-matter tract between the left thalamus and inferior frontal gyrus.
