Thanks to our work, we think the sex peptide signal goes to a region of the fly's brain that is the homolog of the hypothalamus, which has been know for many years to be central in controlling sexual receptivity in vertebrates," explained co-lead author Dr Mark Palfreyman of the Research Institute of Molecular Pathology in Vienna, Austria.
