The ability to target and stimulate neurons brings a
host of benefits including better understanding brain function and
treating neurological diseases. Currently, state-of-the-art
microelectrode arrays (MEAs) can stimulate neurons with high
precision, but they lack cell-type specificity and require invasive
implantation that can result in tissue damage—think stimulators
used to help patients with tremors. Professor of Materials Science
and Engineering, and Biomedical Engineering, Tzahi Cohen-Karni and
his team have been exploring new materials to allow remote
photostimulation, or the use of light to stimulate
cells.
