Excitatory Postsynaptic Potential (EPSPs)

A postsynaptic potential that hyperpolarizes the membrane.

Inhibitory Postsynaptic Potential (IPSPs)

The fact that a stronger stimulus elicits a stronger signal. If there are a greater number of EPSPs compared to IPSPs , a stronger signal will be sent compared to if there were an equal amount.
