Pattern visual-evoked potential and immunohistochemistry results showed that levodopa methyl ester and levodopa treatment shortened P10o wave latency, increased Pleo amplitude, and increased the number of endogenous nerve growth factor-positive cells in visual cortex levels. In particular, the effects of levodopa methyl ester were superior to levodopa treatment.展开更多
