Graphene Sensors Map Brain Electrical Waves to Assess Stroke Damage

Researchers from multiple European institutions have developed graphene micro-transistor arrays to monitor brain tissue health during ischemic stroke by recording cortical spreading depolarizations. These sensors, combined with optical imaging, reveal how blood vessel responses differ between healthy and ischemic brain tissue, potentially worsening stroke outcomes. The study was conducted using two mouse stroke models to better understand secondary injury mechanisms.
