At an inhibitory synapse, neurotransmitter binding opens Cl- and K+ channels, causing hyperpolarization due to Cl- influx and K+ efflux, making an action potential less likely by requiring a larger Na+ influx to reach the threshold.
- neurotransmitter binds to Cl- channels - Cl- channels and K+ channels open - Cl- diffuses in, K+ diffuses out - hyperpolarised - larger influx of Na+ required to form action potential - action potential less likely
