Definitions:

IPSPs

Inhibitory postsynaptic potentials, which are synaptic potentials that make a neuron less likely to generate an action potential, often associated with the flow of negative ions into a cell or positive ions out of a cell.

EPSPs

Excitatory Postsynaptic Potentials are electrical charges that increase the likelihood of a neuron firing an action potential.

Temporal Summation

The summing of several postsynaptic potentials produced when a single presynaptic neuron fires multiple times

Spatial Summation

The process by which multiple synaptic potentials combine within one postsynaptic neuron, potentially leading to an action potential.
