Threshold and suprathreshold correlations for the oral tactile sensory mechanism.

The possible relationship between threshold and suprathreshold responses for the lingual tactile system was investigated. Lingual vibrotactile thresholds and suprathreshold magnitude function exponents were correlated for 26 adult subjects. A statistical analysis of the correlations indicated that there was no significant relationship between thresholds and exponents. Vibrotactile threshold and suprathreshold information may be useful in increasing understanding of the complexities of oral somesthesis.
