title: Impairments and recovery of the spatial and temporal components of a visuomotor pointing movement after unilateral destruction of the dentate nucleus in the baboon.
abstract: In baboons trained to perform visuomotor pointing movements, unilateral electrolytic lesions are performed in the dentate nucleus. The consequences of these lesions on the following movement parameters are then studied:--temporal parameters: reaction time and movement time;--spatial parameters: pointing area and directional errors. From the observations taken 3 months after the dentate nucleus exclusion, a distinction can be made between parameters showing recovery phenomena (reaction time and pointing area) and components definitively affected (movement time and directional error).
