Скачать или смотреть EEG Signal Processing: P300 Analysis, Noise Filtering & Data Challenges

In this video, I dive deep into EEG data analysis using browser-based tools available on https://bionichaos.com. From signal filtering and baseline drift correction to exploring P300 event-related potentials, I break down how we visualize and interpret biomedical data using our in-house simulations and JavaScript-based tools.

I show how joint time-frequency scattering helps with seizure detection in EEG signals, examine the pitfalls of poor impedance in electrode setups, and discuss FFT implementation directly in JavaScript—no libraries required. We also look at the structure and limitations of publicly available datasets, highlighting the impact of missing data channels and ambiguous event labeling.

Whether you're into EEG, ECG, biomedical imaging, or simulation design, this session covers a lot of technical ground while staying rooted in practical insights from real datasets.
