Extended Data Fig. 4: Characteristics of cortical traveling waves during encoding and recall of episodic memory task.
From: The direction of theta and alpha travelling waves modulates human memory processing
(A) Histogram of the peak oscillation frequencies for clusters with TWs. All green histograms are properties measured during encoding and blue during recall. (B) Histogram of the number of electrodes in each cluster. (C) Histogram of the counts of clusters per patient that showed TWs. Most participants had 2 to 4 clusters across different sets of grid and strip electrodes or groups of electrodes with oscillations at different peak frequencies. A few patients had 5 or more. Patients with many clusters often had multiple smaller clusters of 5-6 electrodes in different regions and hemispheres. (D) Distribution of the percentage of single trials that show reliable TWs for individual clusters. (E) Histogram of TW propagation phase velocities across clusters. Black line indicates median. (F) Histogram of TW spatial wavelength.
