Cortical Response to Acute Implantation of the Utah Optrode Array in Macaque Cortex

Advanced Healthcare Materials, EarlyView.
Delivering light deep into the brain over a large volume while causing minimal tissue damage is a major challenge for non‐human primate optogenetics. This study evaluates Utah Optrode Array designs in vivo, revealing how changes in shank geometry, surface texture, and insertion parameters minimize acute damage—offering a path toward high‐precision ...
