Are Cerebellar Lesions Ipsilateral?

Lesions in the cerebellar hemispheres cause deficits in the arm and/or leg ipsilateral to the affected hemisphere (in contrast to lesions of the cerebral hemispheres which cause deficits in the arm and/or leg contralateral to the affected hemisphere).

Why are cerebellar lesions ipsilateral?

Unlike the cerebral cortex, the cerebellum receives input from, and controls output to, the ipsilateral side of the body, and damage to the cerebellum therefore results in deficits to the ipsilateral side of the body.

Are cerebellar signs ipsilateral?

Lesions of the cerebellar hemisphere cause ipsilateral signs.
