Maybe the Three Blind Mice didn’t really need their vision

Hartmann said one of the biggest surprises in her research was finding out how much independent control a rat has over its whiskers. Hartmann’s team found that whiskers do not bend and move the way people typically think– in sync and in a fluid brushing motion. A rat can shut down one side of its whiskers, while the other side goes to work.

Hartmann explained why it is important for scientists to study such seeminglyunusual systems as rat whiskers.
“By studying rat whiskers, what we’re really studying is the neural basis for the sense of touch and motor control. In the long run, understanding the rat’s neural circuits will greatly help us in understanding circuits of the human brain, and helping people with motor and sensing disabilities or injuries.”
