Direct pathway

Definition

In the context of the Central Nervous System within Anatomy and Physiology, the direct pathway is a neural circuit that facilitates the initiation and execution of voluntary motor movements by promoting the activity of motor cortices. It involves specific neurons in the basal ganglia that positively regulate movement through excitatory signals.
