The membrane proximal region (MPR) of AMPA receptor (AMPAR) is needed for receptor trafficking and synaptic plasticity. However, its roles in long-term memory formation are not known. To assess ...

Morphine-induced hyperpolarization of membrane potentials could be reversed by, D-Phe-Cys-Thr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP), a mu receptor antagonist, in the presence of tetrodotoxin.
