When given a choice between food and sex, what would you choose? - via healthing_ca healthing health healthnews canada
Dave Yasvinski,Researchers hope the study of fruit flies will reveal more about the human brain and its impulses.When given a choice between food and sex after being denied both, most individuals will opt for a good meal over a good time, according to a new study that reveals some of the biological factors underlying decision-making., found that when confronted by the age-old behavioural conflict, the impulse to mate was overridden by the urge to eat in experiments on fruit flies.
Researchers found that hunger overpowered other urges in male flies that were separated from food and females for an extended period of time, with the “behavioural tipping point” occurring at around the 15-hour mark of starvation. After satisfying the need for sustenance, male flies returned to more amorous interests, often within a matter of seconds.
“The neurons that tell the fly to go and eat, or to go and mate, are essentially competing with each other,” explains Scott Waddell, a professor at Oxford University who collaborated with researchers. “If the need to eat is most urgent, the feeding neurons will take over, if the threat of starvation is less, then the urge to reproduce will win.”
The team hopes a better understanding of the underlying mechanisms at work in fruit flies will yield new knowledge about the human brain and its impulses, said Saloni Rose, a PhD student and one of the main contributors to the study.
