Background rate versus threshold for 65 afferents evaluated. There was no correlation (r=−0.17, N=63, P=0.05) between these two variables when the two afferents with spike rates higher than 100 spikes s−1 were excluded from the statistical evaluation. With the two units included, the correlation was significant (r=−0.25, N=65, P=0.05).
