Explanation:
Detailed explanation-1: -The indirect pathway, sometimes known as the indirect pathway of movement, is a neuronal circuit through the basal ganglia and several associated nuclei within the central nervous system (CNS) which helps to prevent unwanted muscle contractions from competing with voluntary movements.
Detailed explanation-2: -The “Direct pathway” is comprised of inhibitory projections from the caudate or putamen. Activity in the “Direct pathway” releases or “disinhibits” motor movement by inhibiting the GPI/SNpr. Dopamine, via the nigrostriatal pathway, synapses on striatal neurons that express the D1-family of receptors.
