Psychophysical and cortical measures of tactile sensitivity throughout the body.

Reverse rank-ordered tactile sensitivity for each of the twenty body regions examined, according to psychophysical (2PD threshold) and cortical (area of S1, adjusted for corresponding skin surface area) measures, as reported in previous research. Psychophysical and cortical measures were strongly correlated [r(19) = .65, p = .002]. a[Ref. 23]; b[Ref. 24]; c[Ref. 25]; d[Ref. 26] (esp. Fig. 17, pg. 44). 2PD: two-point discrimination; S1: primary somatosensory cortex.
