Fig. 4: Correlation between sleep indices and reduction of arousal and distress.
From: Sleep’s role in updating aversive autobiographical memories
Scatter plots illustrating the correlation between sleep physiology (SWA and fast spindle density) and reduction of distress associated with the aversive memory (A, C) and arousal measured by HR (B, D) from pre to post. The 1.95% confidence intervals are depicted in grey. *p < 0.05. SWA = slow wave activity (measured at Fz in the spectral band 0.5–4 Hz); fast sleep spindles (13–15 Hz) were measured at Cz and automatically detected during stage N2 and N3.
