To help us drive a car in dense urban environments, our visual system processes complex scenes with effortless ease. Patients suffering from neurodegenerative disorders, like Parkinson’s disease (PD), experience difficulties driving in complex environments. This is because PD patients experience an array of visual disturbances. These include changes in color vision and contrast sensitivity as well as difficulties with complex visual tasks such as object and motion processing. Using behavioral and electrophysiological tools, my research aims to investigate how complex visual information is processed by the brain to guide arm reaching movements. Furthermore, my interests are in investigating how deficits in visual information processing during PD may impair the smooth execution of arm movements.
