Functional tracing of brain circuitry by a novel approach

Grant number: DP130104661 | Funding period: 2013 - 2016



A genetically modified virus is taken up by axon terminals (the 'output' part of a nerve cell) and transported by the cell back to the cell body (its 'input' part). Once there, it makes a protein that makes the cell sensitive to blue light. This new tool may be instrumental in answering questions about nerve connections that cannot be answered in other ways.
