LED Display Guides Surgery with Real-Time Visuals of Brain Activity
SAN DIEGO, May 16, 2024 — During brain surgery, healthy and diseased brain regions are marked with sterile papers to define the margins for a safe operation. These margins are defined through communication between the neurosurgeon and a team of electrophysiologists located in a different part of the operating area. Adding further difficulty, the electrode grids that are used to measure brain activity and identify the boundaries between pathological and functional brain regions have low resolution and limited conformity
