The device combines LEDs and an electrode grid to light up the brain during surgery. It will provide surgeons with real-time visual guidance.
In a groundbreaking development, researchers have invented a new medical device that can make brain surgery safer and more effective.
It is like a thin, flexible sheet covered in tiny LEDs which can be placed directly on the surface of the brain during surgery. Interestingly, the groundwork for this innovation lies in a technology called the Platinum Nanorod Electrode Grid , which acts as a high-resolution sensor array directly placed on the brain’s surface during surgery.. Each LED within the device acts as a tiny mirror and reflects the activity of thousands of neurons. They will do the color-coding of brain regions.
For epilepsy patients, the device can pinpoint the exact source of seizures within the brain. This allows surgeons to either remove the problematic tissue or use carefully targeted electrical stimulation to stop seizures from spreading. “We invented the brain microdisplay to display critical cortical boundaries and guide neurosurgery with precision,” said Shadi Dayeh, the study’s corresponding author and professor at the UCSD Jacobs School of Engineering.
