Role of primate cerebellar hemisphere in voluntary eye movement control revealed by lesion effects.
The anatomical connection between the frontal eye field and the cerebellar hemispheric lobule VII (H-VII) suggests a potential role of the hemisphere in voluntary eye movement control. To reveal the involvement of the hemisphere in smooth pursuit and saccade control, we made a unilateral lesion around H-VII and examined its effects in three Macaca fuscata that were trained to pursue visually a ...
متن کاملRole of monkey cerebellar nuclei in skill for sequential movement.
To examine whether the cerebellum is involved in learning and memory of visuomotor sequences, we trained two monkeys on a sequential button press task and inactivated different portions of the cerebellar nuclei by injecting a small amount of muscimol (gamma-aminobutyric acid agonist). Before the injection experiments started, the monkeys had learned a set of sequences (n = 21 and 12) extensivel...
متن کاملPrediction of complex two-dimensional trajectories by a cerebellar model of smooth pursuit eye movement.
A neural network model based on the anatomy and physiology of the cerebellum is presented that can generate both simple and complex predictive pursuit, while also responding in a feedback mode to visual perturbations from an ongoing trajectory. The model allows the prediction of complex movements by adding two features that are not present in other pursuit models: an array of inputs distributed...
متن کاملMovement in Patients with Cerebellar Ataxia
Objective: To characterize kinematically any systematic aberration in multi-joint movements in cerebellar ataxia. Methods: Nine patients with cerebellar degeneration and nine normal subjects, mobile only at the shoulder and elbow of the right arm, were required to produce left-to-right cross-body linear hand trajectories on the horizontal surface of a digitizing tablet. Nonlinearity indicated f...
متن کاملRapid Eye Movement Sleep
• Rapid eye movement (REM) sleep was first identified by its most obvious feature: rapid eye movements occurring during sleep. In most adult mammals the electroencephalogram (EEG) of the neocortex is low in voltage during REM sleep. The hippocampus exhibits regular high-voltage theta waves throughout REM sleep. • The key brain structure for generating REM sleep is the brainstem, particularly th...
