TL;DR: Non-invasive home EEG sensors detect microvolt electrical fluctuations across five frequency bands: Delta, Theta, Alpha, Beta, and Gamma. Neural tracking methods include consumer EEG headbands, multi-channel headsets, DIY Arduino boards, and hybrid neurofeedback systems. Reliable readings require alcohol-based skin preparation, signal noise reduction, conductive gel, 5-minute baselines, and 4- to 8-week tracking protocols. Measure […]
