title: Activation of M1-like muscarinic receptors is required for the induction of corticostriatal LTP.
abstract: 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.
