565:, though the substantia nigra's role in motor control is indirect; electrical stimulation of the substantia nigra does not result in movement, due to mediation of the striatum in the nigral influence of movement. The pars compacta sends excitatory input to the striatum via D1 pathway that excites and activates the striatum, resulting in the release of GABA onto the globus pallidus to inhibit its inhibitory effects on the thalamic nucleus. This causes the thalamocortical pathways to become excited and transmits motor neuron signals to the cerebral cortex to allow the initiation of movement, which is absent in Parkinson's disease. However, lack of pars compacta neurons has a large influence on movement, as evidenced by the symptoms of Parkinson's. The motor role of the pars compacta may involve fine motor control, as has been confirmed in animal models with lesions in that region. 1120: 1096: 637: 531:. In rats, the frequency of action potentials is roughly 25 Hz. The purpose of these spontaneous action potentials is to inhibit targets of the basal ganglia, and decreases in inhibition are associated with movement. The subthalamic nucleus gives excitatory input that modulates the rate of firing of these spontaneous action potentials. However, lesion of the subthalamic nucleus leads to only a 20% decrease in pars reticulata firing rate, suggesting that the generation of action potentials in the pars reticulata is largely autonomous, as exemplified by the pars reticulata's role in 711:
smaller substantia nigra, specifically in the SNpr. Because the SNpr is connected to the posterior thalamus, ventral thalamus and specifically, the motor cortex, and because participants with Parkinson's disease report having a smaller SNprs (Menke, Jbabdi, Miller, Matthews and Zari, 2010), the small volume of this region may be responsible for motor impairments found in Parkinson's disease patients. This small volume may be responsible for weaker and/or less controlled motor movements, which may result in the tremors often experienced by those with Parkinson's.

The pars compacta is also important in spatial learning, the observations about one's environment and location in space. Lesions in the pars compacta lead to learning deficits in repeating identical movements, and some studies point to its involvement in a dorsal striatal-dependent, response-based memory system that functions relatively independent of the 847:. The mechanism is thought to be via increased dopamine release and decreased GABA release in the nerves of the substantia nigra/striatum. The effect is most pronounced on the chest wall muscles and can lead to impaired ventilation. The condition is most commonly observed in anaesthesia where rapid and high doses of these drugs are given intravenously. 815:

Dysbindin, which has been (controversially) linked to schizophrenia, may regulate dopamine release, and low expression of dysbindin in the substantia nigra may be important in schizophrenia etiology. Due to the changes to the substantia nigra in the schizophrenic brain,

In addition, these neurons form up to five collaterals that branch within both the pars compacta and pars reticulata, likely modulating dopaminergic activity in the pars compacta. 391:

Because of the similarity between amphetamine and trace amines, it is also a substrate for monoamine transporters; as a consequence, it (competitively) inhibits the reuptake of dopamine and other monoamines by competing with them for uptake, as well. 2649:
