"Web3. One way to classify neural inhibition is based on the inhibition being "presynaptic" or "postsynaptic". As far as I understand, the two different types of inhibition refer to the following: Presynaptic inhibition: A neuron N1 is inhibited "indirectly" insofar as the presynaptic excitatory neuron's action on it are dampened.

WebSummation thus allows subthreshold EPSPs to influence action potential production. Likewise, an IPSP generated by an inhibitory synapse (I) can sum (algebraically speaking) with a subthreshold EPSP to reduce its amplitude (E1 + I) or can sum with suprathreshold EPSPs to prevent the postsynaptic neuron from reaching threshold (E1 + I + E2).
