Definitions:

Axons

Long, threadlike structures of neurons that carry nerve impulses away from the cell body.

Dendrites

Branched extensions of a neuron that receive signals from other neurons and transmit them toward the cell body.

Signal Detection Theory

A means to quantify the ability to discern between information-bearing patterns and random noise that is characteristic of much stimuli.

Hit Rate

A measure of the frequency or proportion with which a correct detection or decision is made, often used in signal detection theory and other areas of decision-making research.
