Differential regulation of paired-pulse plasticity following LTP in the dentate gyrus.

abstract：:It is well established that Parkinson's disease leads to impaired learning from reward and enhanced learning from punishment. The administration of dopaminergic medications reverses this learning pattern. However, few studies have investigated the neural underpinnings of these cognitive processes. In this study, using...
