Psio 303 block 1 l12 - Study guides, Class notes & Summaries

An mGluR receptor on the postsynaptic cell membrane has a Go G-protein. If a neurotransmitter causes receptor activation and then Go causes a sodium channel to close, what influence is this action likely to have on membrane potential in the postsynaptic cell? Nn - A hyperpolarizing influence What is a metabotropic receptor? - a type of membrane receptor of eukaryotic cells that acts through a second messenger. What is convergence of neural input ? - several presynaptic neurons synapse with ...
