A dissociation between real and simulated movements in Parkinson's disease.

abstract：:The parkinsonism-inducing neurotoxin 1-methyl-4-phenylpyridine (MPP+) acts through inhibition of complex I of the electron transport chain. Recent evidence suggests that it may also act through inhibition of 2-ketoglutarate dehydrogenase complex (KDHC). We confirmed this observation in isolated rat liver mitochondria ...
