Cortical Control of Smooth Pursuit Eye Movements: Sensory and Motor Components. An fMRI study

Smooth pursuit eye movements (SP) serve to keep a moving object in our fovea, the place of highest visual acuity. For this purpose, the SP system must detect the object moving across our retina (sensory input), process its velocity, and prepare a motor command signal being sent to the eye muscles (motor output), which enables the eyes to follow the object. The purpose of this study is to identify which cortical regions process the sensory input information, which process the motor output signals, and which are related to both processes (possibly sensorimotor transformation sites). For this purpose we measured co…
