Effect of L-DOPA treatment on brain metabolism in the monkey Sokoloff's group used the deoxyglucose method to study many brain phenomena, including the effects of various drugs on cerebral metabolism. A series of studies in the mid-1980s explored the effects of l-dopa in the brains of monkeys with parkinsonism induced by MPTP. This is one of the slides used for presentations. It's a color-coded autoradiograph of a coronal section. It shows clearly that l-dopa increases metabolism in the brains of monkeys with induced parkinsonism, though not much in normal brains.
