S1 Oscillatory Activity: (a) Post-stimulus time-frequency representations showed an early ~20-70 ms low-gamma (γ) ERS. This was followed by a prolonged ERD in alpha (α) and beta (β) power at ~100-300 ms post-stimulus. There was a simultaneous theta (θ) ERS at ~50-200 ms. (b) Beta ERD at 100-300 ms was calculated for each minute of stimulation and demonstrated a trend for decrease over the course of EA stimulation. Similar calculations were made for other frequency bands but did not show significance at the same p < 0.01 level.
