Network-specific resting-state connectivity changes in the premotor-parietal axis in writer's cramp.

•Investigation of FC changes in various sensorimotor ICNs at rest in writer's cramp.•We saw multiple, network-specific FC changes in primary/higher sensorimotor cortices.•This may act as basis of the varying nature of sensorimotor changes during task-fMRI.•Further, findings supporting disrupted cerebellar-basal ganglia interaction were made.•An additional morphometric analysis demonstrated structural cerebellar abnormality.
