Definitions:

Absolute Threshold

The minimum intensity of stimulation required to produce a sensory experience or for a stimulus to be detected 50% of the time.

Just Noticeable Difference

The minimum amount by which stimulus intensity must be changed in order to produce a noticeable variation in sensory experience.

Action Potentials

Quick electrical impulses that travel down the axon of a neuron, triggering the release of neurotransmitters at synapses.

Proximal Stimulation

Proximal stimulation refers to the sensory information received directly from stimuli that are in close proximity to the sensory receptors.
