By harnessing quantum dots—tiny light-emitting semiconductor particles a few billionths of a meter across—researchers at the University of Washington (UW) have developed a new and vastly more targeted way to stimulate neurons in the brain. Being able to switch neurons on and off and monitor how they communicate with one another is crucial for understanding—and, ultimately, treating—a host of brain disorders, including Parkinson's disease, Alzheimer's, and even psychiatric disorders such as severe depression. The research was published today in the Optical Society's (OSA) open-access journal Biomedical Optics Express.
