Relative refractory period- a little later; an AP can be generated if it is larger than normal stimulus.”

Q

What are the effects of the specific neurotransmitters.

A

Some NT are excitatory at some synapses and inhibitory at others; depends on the structure of the NT receptor it binds to. Ach can bind to ionotropic receptors containing cation channels and generate EPSP in the postsynaptic cell. Some inhibitory synapses Ach binds to metabotropic receptors couples to G proteins that open K+ channels_IPSP.
