Direction

La professeure Aarlenne Khan est spécialiste de l'interaction entre l'attention et les mouvements oculaires dans le cerveau sain et malade. Outre ses travaux sur l'ataxie, elle mène, entre autres, des recherches auprès de patients ayant des lésions du cortex pariétal ou qui souffrent de la maladie de Parkinson.
