Role of anticipation and prediction in smooth pursuit eye movement control in Parkinsons disease
Movement Disorders, 06/21/2012
Helmchen C et al. – The authors conclude that Parkinson's disease (PD) patients have difficulties in anticipating future target motion, which may play a role for the mechanisms involved in deficient gait initiation and termination of PD. In contrast, they remain unimpaired in their capacity of building up an internal representation of continuous target motion. This may explain the clinical advantage of medical devices that use visual motion to improve gait initiation.
