From: OPM-MEG reveals dynamics of beta bursts underlying attentional processes in sensory cortex
Pan spectral bursts during the task: (A) Raster plots showing the binary timecourse of the burst state for all trials. Trials are concatenated in the y-axis. The x-axis represents time. White indicates presence of a burst, whereas black delineates the absence of a burst. Left panel shows the left somatosensory cortex, and right panel shows the right. (B) Power spectral density plots for the three HMM states; the blue trace shows the burst state. Again, left and right panels respectively correspond to the left and right somatosensory cortices as indicated by the small brain colourmaps on each corner. These were produced using the AAL atlas brain template in MATLAB (Version R2023a, MathWorks Inc.).
