Understanding presynaptic and postsynaptic inhibition

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.
