Topic: oculomotor vermis

Control of saccadic eye movements, crucial for visual acuity during attention shifts, undergoes adaptation due to internal and external factors, such as fatigue and changing environments, critically depending on the cerebellum. Here we aim to clarify the neural mechanisms underlying saccadic adaptation in two dimensions, particularly the role of the cerebellar Purkinje cells (PC) in movement coding and plasticity. We recorded 56 PCs from the oculomotor vermis of three adult male rhesus monkeys (Macaca Mulatta) during a cross-axis adaptation task comprising three epochs. In the first pre-adapta
