How a Seizure Spreads Electrical Activity Through the Brain 🧠⚡

What the illustration shows

Portrait educational poster titled “How a Seizure Spreads Electrical Activity Through the Brain 🧠⚡”. A large ivory-peach brain is viewed from above against midnight navy. Fine lines connect blue-gray and gold spherical network markers across the two hemispheres. A modest gold cluster on the left is labeled “Illustrative focal network”; several gold markers on the right are labeled “Possible wider recruitment”. Many blue-gray markers remain. These are conceptual groups, not mapped patient regions. A prominent subtitle says a focal seizure can recruit wider brain networks and not every seizure follows this pattern. Below, two schematic brain networks compare limited involvement with wider involvement, linked by “can recruit”. Gold denotes involvement in this example; blue-gray denotes other network context. A separate closeup shows a gold axon ending facing a blue receiving dendrite across a gap, as connection context rather than a seizure-specific cellular sequence. Large notes say “Conceptual network example, not a brain scan or diagnostic map.” and “Not every seizure starts focally or spreads bilaterally.” Gold AllHumanBody.com branding and the full slogan appear on a plain navy footer. A tiny note states AI-assisted educational illustration, not physician reviewed. The thin surface-spanning connections are schematic, not real tract trajectories. Tiny inset details and footer disclosure require zoom.

How to interpret this poster

• Conceptual network, not EEG, current measurement, scan, tract map or universal spread route. No symptoms, first aid, treatment, every-neuron synchrony or causal trigger claims.
• AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
• Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
