@neelmed Completely agree all EEG questions should include calibration settings—thank you for highlighting this. The contributor was aiming to demonstrate hypsarrhythmia, so overlapping waveforms are expected. That said, without voltage info, the EEG cannot be fully interpreted.

@eeg_master Not just for the question. It’s not a good practice to show eegs without calibration and filter settings and certainly not with so much overlap of waveforms. Lower the amplification.

@neelmed You are right. It is not fair to ask this question without these settings. Let me get these for you.

@eeg_master No voltage and time calibration, no filter settings shown. Overamplified eeg!
