Project Description

I built this demo for Piramidal, a company that builds a foundation model for EEG. It replays 23 beds of real pediatric EEG (CHB-MIT, from PhysioNet) as a live monitoring wall.

An open model, SPaRCNet, reads each bed’s last 10 seconds of EEG every 2 seconds. It flags seizures and the four patterns of the ictal-interictal continuum.

Beds in a seizure flash red at the top of a live risk ranking. Click a bed to see its full EEG, the seizure onset and detection times, and its pattern burden.

I used Next.js, React, and TypeScript. Canvas strip charts hold 60 fps across all 23 beds. Not for clinical use.
