WebJul 25, 2024 · The nigrostriatal pathway serves as a basal ganglia input and modulates the direct and indirect pathways. The substantia nigra pars compacta (SNpc) sends dopamine to the striatum via this pathway. As mentioned, the striatum has a population of neurons that are excited by dopamine because they express the D1-family of dopamine receptors … WebThe “basal ganglia” refers to a group of subcortical nuclei within the brain responsible primarily for motor control, as well as other roles such as motor learning, executive functions, emotional behaviours, and play an important role in reward and reinforcement, addictive behaviours and habit formation.
