  • Title: Neurotransmitters in the basal ganglia.
    Author: McGeer EG, Staines WA, McGeer PL.
    Journal: Can J Neurol Sci; 1984 Feb; 11(1 Suppl):89-99. PubMed ID: 6143612.
    Abstract:
    The literature is reviewed on the afferents and efferents of the caudate/putamen, globus pallidus and substantia nigra, and on the neurotransmitters occurring in the various tracts. Emphasis is placed upon the diverse roles played by GABA and glutamate as transmitters in motor pathways and upon the probability that the substantia nigra pars reticulata plays a pivotal role in the output of the basal ganglia. Excessive stimulation of the projection from the pedunculopontine tegmental area to the substantia nigra is shown to cause destruction of dopaminergic neurons in the latter nucleus, suggesting another possible mechanism for cell death in Parkinson's disease.
