Fruit fly sex drive hints at how animals choose behaviors [Phys]

par Frédéric Magné - publié le

Male fruit flies have a mating drive, and its rise and fall is controlled by dopamine levels in one area of the brain, a team of Harvard Medical School neurobiologists has found.
The discovery provides insight into the nature of motivation across species, the researchers said.
"None of us is really interested in flies or their sexual behavior," said Dragana Rogulja, assistant professor of neurobiology at Harvard Medical School and co-senior author of the study. "We’re trying to understand how animals make and carry out decisions to perform or not perform a behavior."
