Inhibitory postsynaptic potentials (IPSPs) are due to the opening of chloride and potassium channels.

Here's a step-by-step explanation:

1. When an inhibitory neurotransmitter (like GABA) binds to its receptor on the postsynaptic neuron, it causes specific ion channels to open.
2. If chloride channels open, chloride ions (which are negatively charged) flow into the neuron, making the inside of the neuron more negative. This moves the membrane potential further from the threshold needed to trigger an action potential, thus inhibiting the neuron.
3. If potassium channels open, potassium ions (which are positively charged) flow out of the neuron, also making the inside of the neuron more negative and inhibiting the neuron.
4. Therefore, the opening of chloride and potassium channels leads to inhibitory postsynaptic potentials.
