The medial cerebellar system receives cortical information from areas 4, 8 and 7 via the ND [62], [63], [38], [56]. The lateral cerebellar system might not have been related only to skilful motor learning via areas 4, 6, 5 and 8 [35], [36], [63], [38], [56], but also to cognitive and language processing via the prefrontal cortico-rubral projection.
