Web13 mrt. 2024 · Placing electrodes directly in the brains of people with Parkinson’s disease revealed a “hyperdirect” pathway between two regions of the brain responsible for movement and cognition, a study reported. This pathway was shown to be important in being able to stop body movements once initiated. The direct pathway, sometimes known as the direct pathway of movement, is a neural pathway within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement. It works in conjunction with the indirect pathway. Both of these pathways are part of the cortico-basal ganglia-thalamo-cortical loop.
