Figure 3.
Evoked oscillatory activity during WM encoding. Evoked beta (top), alpha (middle), and theta (bottom) activity after WM load 1 (left), WM load 2 (center), and WM load 3 (right) is shown for the encoding period of 3 s at posterior electrodes for controls (NC, blue, top row) and patients with EOS (red, middle row) and the group comparison in the frequency range and time window of interest (bottom row). The frequency range and the window of interest (the first sample stimulus for WM load 1, the second stimulus for WM load 2, and the third stimulus for WM load 3 are denoted in bars) are shown. On the far right, mean amplitudes in response to WM load 1, 2, or 3 are shown for the anterior and posterior ROI for patients with EOS (red) and controls (NC, blue). Error bars represent SE.
