Linda Bartoshuk, a University of Florida researcher who studies how taste
perception affects health, knew from earlier research that middle - ear infections can damage the chorda tympani, the
nerve that carries taste information from the front of the tongue to the brain.
After the
nerves that
affect conscious proprioception go, next are the
nerves for voluntary motion (including voluntary control of urination / defecation), followed by the
nerves for superficial pain
perception, and ultimately the
nerves for deep pain
perception (usually tested by applying a strong pinch to the toe).
