Scientists develop device that lights up brain neurons

Gulf Today Report

Scientists at the American University of Arizona developed a device with a diameter of about half a centimetre, to activate brain neurons by delivering light across the skull after implanting it under the skin of the scalp above the concerned neurons.

This can be activated wirelessly, via an external electromagnetic field, so it does not require a battery.

The device's light flashed through the bones and into the brain, stimulating those neurons, and has successfully passed the tests in mice.

Professor Philip Gutroff of the University of Arizona said, "The device allows scientists to perform a wide range of experiments which enables the science community to make faster progress to reveal principles of brain working and to develop and test treatments in micro-environments."

Gutroff added that small, implanted LEDs were used to light up these neurons, thereby activating them on demand.
