Fig. 2: Neurophysiological effects of closed-loop auditory stimulation.
From: Modulating sleep: slow oscillation and spindle stimulation effects on physiology and memory
CLAS of both slow oscillations (detected at Fpz) and sleep spindles (detected at Cz) enhances (a) slow wave activity (0.1–4 Hz) and (b) spindle band activity (11–16 Hz). Black vertical lines represent stimulation onset. Dashed vertical lines represent the onset of spindle detection in the delayed stimulation condition (SPd). Solid lines indicate group mean and shaded lines represent standard error of the mean. Grey shaded rectangles delineate time windows used to extract the magnitude of evoked activity in each frequency band. Statistical differences comparing stimulated to unstimulated sleep (i.e., Sleep condition) are represented in the bottom panels. Solid areas represent corrected p-values and coloured shading represent uncorrected p-values.
