Overview
Mermaid diagram (expand to render)
Nigrostriatal pathway dopaminergic neurons are a critical subset of substantia nigra pars compacta (SNc) neurons that project to the dorsal striatum (caudate nucleus and putamen). These neurons form the nigrostriatal pathway, which is essential for motor control and is devastated in Parkinson's disease. [@damier1999]
