ARIA EEG Workspace

PARTIAL

Four synchronized panels

• Trace strip — 23-channel EEG scroller with seizure markers.
• Scalp topomap — top-down voltage interpolation with propagation ripple.
• Cortical surface — real fsaverage brain mesh with dSPM source estimates colored on cortex.
• Timeline — scrubber, play/pause, snap-to-marker.

Single-source-of-clock

One requestAnimationFrame hook drives all four panels — no drift, no jitter across the synchronized views.

Clinical Summary Strip

Demarest format: onset · spread · source · confidence.

MAVS clinician chat

Disciplined clinician prompts. Never throws — falls back through static analysis → local synthesis → empty-but-friendly response. Ctrl+Shift+F enters panic mode which flips the workspace fully offline.

Locked honesty terminology. Spatial views use: "Scalp Activity Map", "Estimated Source View", "Template-brain estimate", "Derived from scalp EEG", "Clinician review recommended". Provenance Badges (Simulated · Local · Manual · Not Real-Time) are always visible. Not for clinical diagnostic use.

CHB-MIT ODC-BY attribution is always visible in the workspace footer when a CHB-MIT-derived clip is loaded.

Status

PARTIAL. Core playback, source-estimate rendering, and MAVS chat are live. Clip library is limited (CHB-MIT demonstration data plus internal test clips). Availability depends on build configuration.

Why it exists

Reviewing a seizure typically requires concurrent access to trace, scalp topography, and source-estimate views. ARIA's workspace is an integrated, locally run alternative — with deliberately locked terminology so research-grade outputs cannot be confused with clinical diagnostic reports.
