Code repository. This repo holds the analysis code; the de-identified data live in the bdsp.io credentialed release (data → AWS, code → GitHub): bdsp.io/content/xxdpcilmmlr5ryqjze1m/1.0.0 · DOI 10.60508/ndmj-wz29 · s3://bdsp-opendata-credentialed/eeg-spectrogram-atlas/

MATLAB code and a de-identified labeled EEG/qEEG teaching dataset for:

Ng MC, Jing J, Westover MB. A Primer on EEG Spectrograms. J Clin Neurophysiol 2022;39(3):177-183. doi:10.1097/WNP.0000000000000736 · PMID 34510095

A teaching atlas pairing raw EEG with its quantitative-EEG (qEEG) spectrogram across 224 labeled examples — normal rhythms, sleep, seizures, and ictal-interictal-continuum patterns (LPD/GPD/LRDA/GRDA, etc.) — to help clinicians learn to read spectrograms "from first principles."

Data

SegMats/ — 224 self-contained labeled segments (paired EEG + 1-hour qEEG spectrogram), named by pattern; no names, MRNs, or dates (recording timestamps removed). See DATA_SOURCE.md.
