Anticipation and navigation: Do your legs know what your tongue is doing?

Scientists create a virtual reality environment to study how rats navigate and anticipate rewards. The results show that rats prefer to use visual cues for navigation, while their legs work in harmony with their anticipation of food. In contrast, auditory cues alone lead to confusion and random movement.
