We studied the role of endogenous acetylcholine (Ach) in corticostriatal long-term potentiation (LTP). The muscarinic receptor antagonists scopolamine and pirenzepine fully prevented the induction of LTP suggesting that the activation of M1-like muscarinic receptors is a crucial event in the conditioning phase of this form of synaptic plasticity.
我们研究了内源性乙酰胆碱(Ach)在皮质纹状体长期增强(LTP)中的作用。毒蕈碱受体拮抗剂东莨菪碱和哌仑西平完全阻止了LTP的诱导,这表明类似M1的毒蕈碱受体的激活是这种形式的突触可塑性调节阶段的关键事件。
