When we touch something, how do sensations from our hands get translated into perceptions by our brains? Meet two scientists who are trying to answer that question with a curious tool: rat whiskers. Just like hands are to humans, whiskers are rats’ primary sensors of touch. Analyzing how whisker sensations get processed by rats’ brains is providing a powerful model that’s helping reveal the mysteries of our own sense of touch.
