This type of sensor could be used to map light emitted by optical fibers implanted in the brain, such as the fibers used to stimulate neurons during optogenetic experiments.

Using a specialized MRI sensor, MIT researchers have shown that they can detect light deep within tissues such as the brain.

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

Experiments conducted using the photosensor system indicated excellent optical properties, including high tunability and responsiveness over a broad range of light.
