Neural Control of Coordinated Action

We are grateful to Mihail Chemiakin for allowing the use of his artwork.


Accomplishment of daily tasks depends upon interactions between individuals and their environment. These interactions require sensory processing leading to perception, and the development of internal representations of the external world by combining sensory information with cognitive processes like memory and attention. However, these high level processes are not the only end-point of sensory and cognitive processing. Information about the world must also be processed in order to produce behavior: coordinated motor acts. These actions form the basis for nearly all critical functions of living organisms: orientation, navigation, interaction with objects in the environment, communication. The control of movement, the integration of sensory information and the transformations required for coordination of complex behaviors, and mechanisms implemented by structures in the brainstem, cerebellum, cortex and basal ganglia in mediating these processes are critical functions of the healthy nervous system and often present the most debilitating deficits when lost due to neural damage or disease.
