Document Summary
Neuroscience 324: systems neuroscience motor systems: descending motor control: voluntary control, posterior parietal cortex (state and goal estimation, premotor cortical regions (task selection, primary motor cortex (control policy) We have the ability to work with objects and interact with the world. This voluntary behavior is driven by the cerebral cortex. Use as many sources as possible to estimate present body position and motion (proprioception, cutaneous, visual, etc. , as well as internal feedback). Similar process to state estimation except related to the present position and motion of the goal. Decisional processes based on internal needs/desires and external sensory information that selects the behavioural goal of interest. The set of rules to convert the present state of the body into motor commands to attain a behavioural goal. Do not need to know names of different parietal cortical regions. Integration of information on sensory modalities to define where you are in the world and where objects are in the world.
