Fig. 3: Effect of cueing during slow wave sleep.
From: Both slow wave and rapid eye movement sleep contribute to emotional memory consolidation
Time-frequency response to cue presentation during SWS at electrode Cz, in E-SWS (A) and N-SWS (B). Time zero represents the initiation of sound presentation during sleep. Black contour lines highlight significant clusters of activation (p < 0.05, FDR adjusted). In E-SWS, the average valence of the emotional sounds cued during sleep was correlated with the cluster-averaged time frequency activity in the 2–8 Hz response (delta-theta; C). Delta-theta power also showed a positive correlation with CB, which did not survive correction for multiple comparisons (D). The valence of emotional sounds was also significantly correlated with the spindle band (12–19 Hz) response (E), which suggested that emotional valence modified spindle activity. This was further supported by the higher power in the same cluster in response to emotional sounds compared to neutral sounds (E-SWS vs. N-SWS; F; means and standard errors are displayed). **p < 0.01.
