Inhibitory postsynaptic potentials (IPSPs) are associated with **hyperpolarization of the cell membrane**.
This occurs when neurotransmitters bind to receptors that open ion channels, allowing negatively charged ions to enter the cell or positively charged ions to leave, making the inside of the cell more negative and moving it further away from the threshold for action potential generation.
