Benjamin de Bivort’s lab at Harvard University developed a device called the fly-vac to study individual behavior. Upon entering a chamber, the fly must choose to walk toward the light or dark end. A vacuum then sucks it back to the starting point, and it makes the choice again.

In a device in Benjamin de Bivort’s lab at Harvard University, a fly wanders through a tiny Y-shaped maze, choosing at the Y’s vertex whether to walk left or right. This array of Y-mazes allows researchers to track individual behavior in many flies simultaneously.
