Definitions:

Graded Potential

A shift in the electrical charge across a neuron's membrane, varying in magnitude and not following the all-or-nothing principle.

Excitatory Postsynaptic Potential

A temporary increase in postsynaptic membrane potential due to the flow of positively charged ions into the postsynaptic cell, making it more likely for the neuron to fire an action potential.

Postsynaptic Neuron

A neuron that receives a signal (via neurotransmitter molecules) from another neuron at a synapse.

Inhibitory Postsynaptic Potential

A decrease in the potential of the postsynaptic neuronal membrane, making it less likely to generate an action potential.
