Fig. 2From: Comparative study of striatum GABA concentrations and magnetic resonance spectroscopic imaging in Parkinson's disease monkeysa The striatum level of frozen brain sections of PD monkeys. The anatomy of the striatum is shown. b The midbrain substantia nigra of the MPTP injection contralateral of the PD monkeys with TH-positive dopaminergic neuron cells (TH Stain, × 20). c The midbrain substantia nigra of the MPTP injured side of the PD monkeys (TH Stain, × 20). The number of TH-positive dopaminergic neuron cells in the MPTP injured side was significantly reduced, and the residual nerves denaturatedBack to article page
