Direction Neurons

Afferent neurons convey information from tissues and organs into the central nervous system and are sometimes also called sensory neurons.

Efferent neurons transmit signals from the central nervous system to the effector cells and are sometimes called motor neurons.

Interneurons connect neurons within specific regions of the central nervous system.

Afferent and efferent also refer generally to neurons that, respectively, bring information to or send information from the brain region.
