How you can make a fruit fly eat veggies (transcript)
Summary
I see. It's interesting that taste buds of fruit flies are very similar to ours. Taste buds are made up of specialized neurons and when we eat something that is, for example, sweet taste, those taste neurons will fire a signal to the brain.
Its signal like lights is the trigger that we love sweet taste.
Now, the revolutionary new tool can send a signal to the brain of fruit flies when they eat another food that is not sweet taste. They become loving another food.
The tool is optogenetics that is thought to work in humans, the study has to continue, though.
It means that a lot of children don't like to eat veggies though it can be adjusted by optogenetics.
