Optogenetic Tool Guides Brain Mapping
PASADENA, Calif., Sept. 22, 2014 — A new optogenetics technique could help map neural networks in living organisms. Developed by a team at Caltech, the technique offers a clear view of the brain’s circuitry in action, from the moment a neuron fires to the resulting behavior in the whole organism. “Our overarching goal for this tool was to achieve sensing of neuronal activity with light rather than traditional electrophysiology,” said Dr. Viviana Gradinaru, an assistant professor of biology and...
