A record of the electric changes occurring in the vagus nerve.

The vagus nerve supplies nerve fibers to the pharynx (throat), larynx (voice box), trachea (windpipe), lungs, heart, esophagus, and the intestinal tract as far as the transverse portion of the colon. This nerve also brings sensory information back to the brain from the ear, tongue, pharynx, and larynx.

The term vagus (Latin for "wandering") is appropriate because the "vagus nerve" wanders all the way down from the brainstem to the colon, a long wandering way.
