A tiny device puts researchers one step closer to developing new treatments for depression, chronic pain, epilepsy, and more. It is all thanks to University of Arizona engineering researchers. Dr. Philipp Gutruf, a biomedical engineering assistant professor at UArizona is one of the researchers who helped develop the device. This new tool gives a better understanding of how the brain works, by shining light at specific neurons in the brain to suppress or exciting activity. This method called optogenetics allows scientists to develop and test potential cures for illnesses such as neurodegenerative diseases.
