Definitions:

Typical Neuron

A cell of the nervous system, characterized by its ability to receive and transmit electrical signals throughout the body.

EPSPs

Excitatory Postsynaptic Potentials, which are temporary increases in postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell.

IPSPs

Inhibitory postsynaptic potentials, a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.

Action Potentials

Rapid, temporary changes in the electrical charge of a cell's membrane, allowing for the transmission of signals along neurons.
