Article Title: Shifting Baselines: Longitudinal Reductions in EEG Beta Band Power Characterize Resting Brain Activity with Intensive Meditation
doi: 10.1007/s12671-022-01974-9
Figure Lengend Snippet: Identified clusters of current source density (CSD) power change across retreat in ( A ) Retreat 1 training participants, n = 25; ( B ) Retreat 1 waitlist controls, n = 27; and ( C ) Retreat 2 training participants (previously waitlist controls), n = 26. The asterisk (*) indicates electrodes that comprise a significant cluster. All cluster p s < 0.01. For each panel, the leftmost maps depict cluster statistic F -values; the right upper maps depict CSD beta power at pre-, mid-, and post-retreat; and the right lower maps depict raw subtracted differences in CSD power between assessments (e.g., “Pre to Post” = post – pre)
Article Snippet: We used the MATLAB CSD Toolbox ( http://psychophysiology.cpmc.columbia.edu/Software/CSDtoolbox ; Kayser & Tenke, ), to transform data from the standardized 73-channel montage into a reference-free estimation of scalp current source density (CSD) using spherical spline interpolation (Perrin et al., ).
