Treating brain diseases is extraordinarily challenging, because drugs often work poorly and implants require risky surgery that can jeopardize critical brain functions. A group at MIT has sought a different approach, using the natural ability of living cells to detect diseased brain areas and ferry microscopic electronic devices directly to these regions. These devices, smaller than a single cell, can then be remotely activated with infrared light to modulate local brain activity.
