This study investigates the distinct contributions of the cerebellum to intrinsic connectivity networks (ICNs) using resting-state functional connectivity MRI. The cerebellum, particularly the neocerebellum (crus I and II), is found to participate in several nonmotor systems, including executive control networks, the salience network, and the default-mode network. The sensorimotor cerebellum (lobules V–VI) shows little to no overlap with these cognitive ICNs. The neocerebellum, especially lobule IX, is involved in the default-mode network, which is implicated in episodic memory and self-reflection. The study highlights the role of the cerebellum in higher cognitive functions and suggests that the neocerebellum may form part of parallel cortico-cerebellar loops involved in executive control, salience detection, and episodic memory.This study investigates the distinct contributions of the cerebellum to intrinsic connectivity networks (ICNs) using resting-state functional connectivity MRI.
