BOLD responses in the posterior cerebellum differ when a motor task has a proprioception component

The cerebellum receives proprioceptive information from the body, as well as tactile input. Here, we aimed to separate the proprioceptive BOLD responses from the motor/somatosensory clusters in the human cerebellum. Regions responding to a fingertapping task and a motion task requiring proprioceptive information were found to differ in the posterior cerebellum. Using high resolution 7T functional MRI, all proprioceptive clusters in lobule VIII of the cerebellum were found to be positioned medial to regions responding to the simple tapping task.
