Metabotropic glutamate receptor subtype 7 ablation causes deficit in fear response and conditioned taste aversion.

Abstract

Metabotropic glutamate receptors (mGluRs) consist of eight different subtypes and exert their effects on second messengers and ion channels via G-proteins. The function of individual mGluR subtypes in the CNS, however, largely remains to be clarified. We examined the fear response of freezing after electric shock in wild-type and mGluR7(-/-) knockout… (More)
