Abstract

When making a reach movement, sensory information about the object and the motor plan associated to the upcoming reach coincide in space. In order to study how both these types of representations are represented across the brain, we implemented a paradigm that differentiates visual and motor information of an action by comparing reach movements with swipe movements. Differently from reach movements, during swipe movements, participants do not physically start the movement on the object location. Hence, the visual and motor information about a future action are separated. We found that, during the planning period, the primary visual cortex represents both visual and motor information associated with a motor movement. The parietal reach region, involved in the planning and control of reach movements, represents the motor goal of a movement. The primary motor cortex represents both visual and motor components of an upcoming motor movement.
