Recorded from subject 21 during chunk recall experiment with Biosemi Mk II system, 32 electrodes + 4 EOGs + 2 mastoids. Original sampling rate: 8000 Hz. Downsampled to 128 Hz. Referenced on-line to mastoids. Filtered off-line 0.01 to 30 Hz with Butterworth filter in Analyzer v. 1.05. Epoch length is 192. There are 10 4-word sequences of the original 432 (thus 10 items * 192 samples per item = 1920 data points).
