Could fruit flies help determine extent of player's concussion?

The Los Angeles Times reported on a study that shows work with fruit flies may provide answers to concussions sustained by football players.

Geneticist Barry Ganetzky at the University of Wisconsin-Madison medical school said it starts with swatting a few fruit flies and looking at their unique brain matter.

They then started whacking flies, opening a world of information about brain tissue and genetics. Their goal is to find actual markers that show the extent of the concussion rather than asking questions or checking balance.
