IPSP

IPSP is the inhibitory postsynaptic potential, which  hyperpolarizes postsynaptic membrane.

• the neurotransmitter is released by inhibitory synapse

Events that occur in postsynaptic membrane:

1. Chloride ions will enter postsynaptic membrane

2. Potassium ions will leave postsynaptic membrane

3. Small hyperpolarization occurs, leading to diminishing graded potential
