inhibitory potential

What Are Excitatory And Inhibitory Postsynaptic Potentials? Postsynaptic potentials are graded changes in the membrane potential of a postsynaptic synapse. … Excitatory postsynaptic potentials (EPSP) bring the neuron’s potential closer to its firing threshold. Inhibitory postsynaptic potentials (IPSP) change the charge across the membrane to be further from the firing threshold. What is excitatory and
