Webatlas eeg is a language of its own Once you've got the electrodes in place, montage chosen, and the study started, its your job to interpret and communicate the EEG findings. The first step is learning how to differentiate the many waveforms you'll come across, and the vocabulary you need to communicate what you see. WebWhen we integrated all negative and positive amplitude/power data in five EEG bands (delta, theta, alpha, beta, gamma), a few relative power results became huge (i.e., 440%(44.44) or even over 1000%).
