There was no significant interaction of condition and night for the ON-OFF difference of all windows with more than two stimulations ( F cond x night (6,141.8) = 1.62, p = 0.15), the main factor condition was highly significant ( F cond(1,12.6) = 19.76, p = 7.1 × 10 −4 ) indicating that the lowSWA enhancement was persistent across 7 nights.
