Scientists have developed a special device for the thermogenetic control of flies. This tool, called FlyMAD, enabled the scientists to target light or heat to specific body regions of flies in motion and to analyse the animals' brain cells. Compared to other techniques, FlyMAD allows highly improved temporal resolution. Using the new technology, scientists got new insight into the role of two neuronal cell types in courtship behavior of flies.
