G-protein coupled receptors (GPCRs) play a paramount role in diverse brain functions. This voltage dependent potentiation is abolished in mutant animals expressing a voltage independent receptor Depolarization alone, without a muscarinic agonist, results in a nicotinic ionotropic receptor potentiation that is mediated by muscarinic receptor voltage dependency. Finally, muscarinic receptor voltage independence causes a strong behavioral effect of increased odor
