Emotional fruit flies offer clues to ADHD – Futurity. CALTECH (US)—Researchers have uncovered evidence of a primitive emotion-like behavior in the fruit fly Drosophila melanogaster. The findings may be relevant to the relationship between the neurotransmitter dopamine and attention deficit hyperactivity disorder (ADHD) …
Can flies have ADHD?
The findings provide new clues into the neurological basis of attention deficit hyperactivity disorder (ADHD). In the study, which was led by Caltech postdoctoral fellow Tim Lebestky, researchers exposed flies to a series of brief air puffs and identified flies with an abnormally exaggerated hyperactivity response.
Do fruit flies have a short attention span?
Earlier studies have shown that the short-term memory of fruit flies declines with age and that a protein is involved in this process which is similar to that playing a role in humans. In the new study, Tammo Krause and Laura Spindler analyzed the body-size memory of Drosophila.
How long is a fruit flies attention span?
The selective brain response to novel images lasted on average 9–12 seconds in wild-type flies, or about 3–4 exposures (cycles) of the two image choices rotating around the flies at 0.33 Hz.
Why are there fruit flies in my house?
Fruit flies are common in homes, restaurants, supermarkets and wherever else food is allowed to rot and ferment. … Fruit flies are especially attracted to ripened fruits and vegetables in the kitchen. But they also will breed in drains, garbage disposals, empty bottles and cans, trash containers, mops and cleaning rags.

Do fruit flies have good memory?
Amazingly, fruit flies can learn simple tasks, they can form memories, and they can also forget, just as we do. Just like human brains, fly brains are made up mainly of cells called neurons.
Why do fruit flies fight?
D. It may surprise some people to learn that fruit flies fight. But male Drosophila melanogaster (more accurately called “vinegar flies”) do fight–to gain access to resources such as food or females.
Are humans related to fruit flies?
Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA’s Ames Research Center. “About 61% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues.”
