| Description: | The posterior parietal cortex of the brain lies between the sensory and the movement regions of the cerebral cortex and serves as a bridge from sensation to action. Dr. Andersen’s lab has found that an anatomical map of plans exists within this area, and that one part is devoted to planning eye movements and another part to planning arm movements. Action plans in the arm movement area exist in a cognitive form, specifying the goal of the intended movement rather than particular signals to various muscle groups. Andersen’s lab has used the information gained about parietal cortex to begin development of a cognitive-based neural prosthesis for paralyzed patients.
