Monkeys were required to press a lever rapidly for food, using either the right or the left hand. After stable baseline performance was established, MPTP (N-methyl-4-phenyl-2,3,5,6-tetrahydropyridine) was injected into the internal carotid of one side via a transfemoral catheter. The onset and time course of clinically severe, Parkinson-like symptoms were paralleled by a significant decrease of bar-pressing activity in the side contralateral to injection, while the forelimb in the unaffected side continued normal pressing. The unilaterality of effects was confirmed biochemically after sacrifice by a 95% drop in striatal dopamine (DA) levels of the injected compared to the uninjected hemisphere. The results show that hemiparkinsonism achieved by carotid injection is very stable; that normal motor behavior is maintained on the unaffected side and that goal-achieving strategies remain active, but that the affected side is unable to execute the task unless extrinsic levodopa is provided.

D010302 Parkinson Disease, Secondary Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition. Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form.

D003342 Corpus Striatum Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

D004298 Dopamine One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
