Definition

In nervous systems, afferent signals or nerve fibers carry information toward the brain or a particular brain structure. A touch or painful stimulus, for example, creates a sensation in the brain, only after information about the stimulus travels there via afferent nerve pathways. Efferent nerves and signals carry information away from the brain or a particular brain structure.
