A photograph of a computer monitor displaying EEG brain-wave software. The top row shows colour-mapped topographic brain maps labelled Delta, Theta, Alpha, SMR, Theta Power, Beta1 Power and Theta/Beta Power, with a Mean Freq. panel at the upper right. Below, wavy multi-channel traces are plotted in dark blue on a white background, with channel labels such as FP1-(A1), FP2-(A1), F7-(A1), Cz-(A1) and O1-(A1) on the left and a timeline reading 00:36 to 00:50 along the bottom. The room around the screen is dark. No people are visible.
