Tremor-related activity originates at internal pallidal globus (GPi), which propagate to cortex. Cortex and ventral intermediate nucleus of thalamus (VIM) form a circuit, which is possible the base of tremor-related oscillation. Cerebellum also projects to VIM, this projection possibly modulate amplitude of tremor, while cerebellum was modulated by cerebral cortex. COR cortex, CER cerebellum. Orange arrows indicate projections within cerebello-thalamo-cortical circuit, blue arrow indicates projection from GPi to cortex.
