The correlation between frontal slow spindle density development and cognitive abilities was also present for the experimental night but failed to reach significance (r s (34) = 0.32, p = 0.062).

However, memory decliners significantly increased their slow spindle density ( t (19) = −2.54, p = 0.020†, d = −0.16) and showed a trend to decrease their fast spindle density from baseline to experimental night ( t (19) = 1.83, p = 0.082, d = 0.09).
