Stimulating Specific Neurons with Light
A new, noninvasive method to control neurons uses the unique optical and electrical properties of quantum dots (QDs).
Optically excited quantum dots in close proximity to a cell control the opening of ion channels.
A new, noninvasive method to control neurons uses the unique optical and electrical properties of quantum dots (QDs). Researchers at the University of Washington (U.S.A.) showed that neurons and other cells changed their behavior in specific ways when nearby QDs were optically excited (Biomed. Opt. Express 3, 447). The new method provides a tool that could target particular cell types, which would help researchers investigating brain function, including research into Parkinson’s disease, Alzheimer’s and depression.
