Figure Lengend Snippet: Alpha lateralization in the presearch period. A , normalized time course of alpha for the 1,000 ms prior to search onset. Shading represents 95% confidence interval of the mean. Solid green bars at the bottom of the figure represent significant clusters detected by cluster-based analysis testing for differences from zero. Gray shaded area covers the −500 to −200 ms window used in panel C . B , Topography of alpha following averaging over our frequency bins. Black dots represent selected electrodes of interest. C , Averaged alpha lateralization in the prestimulus period −500 to −300 ms prior to search onset. Scores represent HP minus LP, and thus a positive score represents more alpha in the hemisphere contralateral to the expected distractor location. Because this is a normalized score, values represent percentage differences between conditions (out of 1).
Article Snippet: EEG data was recorded with default Biosemi settings at a sampling rate of 512 Hz using a 64-electrode cap with electrodes placed according to the international 10–10 system (Biosemi ActiveTwo system; Biosemi.com) with two reference electrodes attached to the mastoids.
