Hemifacial spasm (HFS) is a motor disorder. The purpose of this study was to investigate the functional alterations of the cortical-striatal network in HFS using resting-state fMRI. To sum up, these data suggest that HFS may lead to an alteration of neural activity of the cortical-striatal loop.

Fig. 1: Differences of the cortical-striatal FC in patients with HFS compared to healthy controls. The FC between striatal subregions and both motor and emotion-related cortex was statistically different between the two groups (GRF correction, voxel P < 0.005, cluster P < 0.05). The yellow dots in the brain represent the seeds of striatal subregions. The red regions represent the increased FC between seeds and cortexes, while the blue areas represent a decreased FC. The color bar represents the t value.
