Detection of dopaminergic cell loss and neural transplantation using pharmacological MRI, PET and behavioral assessment.

abstract：:Short-term exposure of primary cultures of cerebellar granule cells from neonatal rat brain to high concentrations of glutamate results in neuronal degeneration. We found that glutamate, before causing neuronal degeneration, induced a significant increase of Tau protein immunostaining. Time-course experiments revealed...
