Definitions:

Graded Potential

A shift in electrical charge across a neuron's membrane, varying in magnitude, that can initiate an action potential if it reaches a threshold.

Action Potential

A rapid, temporary change in a membrane potential across a cell's membrane, leading to the transmission of nerve impulses.

Spatial Summation

The summing of several postsynaptic potentials resulting when several presynaptic neurons release neurotransmitter simultaneously. Compare with temporal summation.

Presynaptic Neurons

Neurons that send signals to a synaptic gap, initiating neurotransmitter release for neuron-to-neuron communication.
