Summary

Walking a straight line or steering a car down a road may seem effortless, but your brain has to perform a difficult computation to keep you on course. The images of oncoming objects provide a clue to where you are headed, because their images appear to expand from a central point. But that point doesn't stay fixed on your retina, because your eyes are continually moving about. Results reported on page 1544 by a research team help explain how the brain compensates: The researchers have found individual neurons that combine visual information with information about eye movements to calculate the correct heading.
