Amygdala Changes in Chronic Insomnia and Their Association with Sleep and Anxiety Symptoms: Insight from Shape Analysis

Figure 1

The localized shape differences between HC and CID groups using vertex-wise surface analyses of the amygdala are shown. The regions in orange indicate the areas shown to be smaller in patients with CID than in those in HC group. (a) The left amygdala group differences are in the superficial and basolateral nuclei of the amygdala. (b) The right amygdala group differences are in the basolateral nuclei of the amygdala. Abbreviations: CID: chronic insomnia disorder; HC: healthy control; Corr: TFCE corrected; Raw: raw results; TFCE: threshold-free cluster enhancement; A: anterior; P: posterior; S: superior; I: inferior.
