A quantitative physical model of the TMS-induced discharge artifacts in EEG
Fig 12
TMS-evoked responses due to stimulation of the right motor cortex.
(A) Artifact fits (colored) to data (gray) of a single trial. (B) The fitted artifacts and data on a longer time scale. (C) Log-log plot of the artifact fits. (D) The same data with the artifact fits subtracted. The first 1.6 ms, for which data could not be reconstructed, was marked as gray area. (E-F) Electrodes Cz (red), C2 (green), C4 (blue) of the filtered single trial and of the average over 20 filtered trials (thin and thick lines, respectively). Filtering: 1 Hz high-pass, 50 Hz notch. TMS-evoked potentials as reported in the literature are marked at 15, 30, 45, 60, 100, and 180 ms. All data are average-referenced.
