This paper describes a technique for the evaluation of lingual sensitivity. Surface electrodes were used to administer short electrical pulses to the tip, midline dorsum, and lateral margins of the tongue of five normal adolescents. The tongue tip was more sensitive than the dorsum, in an approximate 2:1 ratio. Differences in sensitivity among the areas of the dorsum are of smaller magnitude and not consistent from one day to the next. Neither the right nor the left side, nor the sides corresponding to the dominant and the nondominant hand showed consistent evidences of greater sensitivity.
