In the Central Nervous System (CNS)

Many inputs from hundreds of other neurons are received by a single neruon which then can form synapses with many thousands of other cells.

Type of Potentials

Among these synapses on a single neuron, some get excited when others get inhibited. In the excitatory synapse, neurotransmitter is released which then causes a small depolarisation within the postsynaptic membrane, naming: excitatory postsynaptic potential (EPSP).

On the other hand, the neurotransmitter which is released from an inhibitory synapse causes a small hyperpolarization called: an inhibitory postsynaptic potential (IPSP) [1].
