Median power dissipation before and after stimulation, and same-cell percentage changes (interquartile ranges given in parentheses). (In the first two rows, data are given for the subpopulations exhibiting single- or multiple-frequency beat characteristics post-stimulation. For details on the symbols (*, ^†), see table 1. The change in power dissipation for the single-frequency subpopulation is also borderline statistically significant (p=0.050).)
