Definitions:

EPSPs

Stands for Excitatory Postsynaptic Potentials, which are temporary increases in neuron membrane potential, making it more likely to fire an action potential.

Temporal Summation

Addition of one graded potential to another that occur close in time.

Spatial Summation

Spatial summation refers to the process where multiple synaptic inputs, predominantly from separate neurons, combine within a single neuron, potentially leading to an action potential if threshold is reached.

IPSPs

Short for Inhibitory Postsynaptic Potentials, these are electrical changes in the postsynaptic neuron that make it less likely to generate an action potential, thereby inhibiting the neuron.
