Shunting inhibition is a form of synaptic inhibition in which activation of typically GABAA (or glycine) receptors increases a neuron’s membrane conductance, which can decrease input resistance and the membrane time constant, causing coincident excitatory currents to be “shunted” but not necessarily hyperpolarized. Shunting can occur even when GABA is depolarizing (relative to resting) because conductance increases reduce the voltage response to excitatory input.
