Fig. 5: MEG-Ripple and EEG low-frequency coupling results.
From: Physical activity simultaneously improves working memory and ripple-spindle coupling
A (left) Grand-averaged slow oscillations around the ripple peak compared to the shuffled peak. The dots at the top represent slow oscillation amplitude peaks and troughs from individual subjects. The red dots indicate amplitude peaks, while the pink dots indicate troughs. Error bars indicate the standard error of the mean. (right): The slow oscillations around the ripple peak from different sessions. The blue color represents the rest session, and the red color represents the PA session. B (left): Phase distribution of low frequency around the ripple peak. (right upper): The phase distribution from 14 to 16 Hz from different sessions and the dominant phase from individual subjects. B (right lower): Average dominant phases across sessions. (n = 21; *P < 0.05). C The ripple density during the ‘in-spindle’ and ‘out-of-spindle’ phases is plotted separately for the PA and rest sessions. Red denotes PA session data, while blue represents rest session data. Error bars indicate the standard error of the mean. (n = 21; **P < 0.01, n.s.: not statistically significant). D Ripple likelihood around the spindle onset. The time 0 represents the spindle onset.
