Inhibitory postsynaptic potentials (IPSPs) serve to decrease the likelihood that a neuron will fire an action potential by making the inside of the neuron more negatively charged compared to the outside. Without IPSPs, there would be less inhibition, making it easier for a neuron to reach the threshold needed to fire an action potential.
