Area cooled is surface area of cooling footprint on cortex. Sites with “changed” response are defined as those with any statistically significant change in the neuronal response to stimulation at 1 or more sites on the hand during the cold epoch. Up to 3 deactivation tests (cooling of areas 5L, 7b, and M1) could be conducted at a single recording site; therefore the deactivation test totals here are often greater than the totals for recording sites examined with cooling in Table 2 (e.g., grand totals of 80 and 58, respectively).
