These boosts are made for walkin': Visual system amplifier directly activated by locomotion

The body may get help in fast-changing situations from a specialized brain circuit that causes visual system neurons to fire more strongly during locomotion, neuroscientists have discovered. It has long been known that nerve cells in the visual system fire more strongly when we pay close attention to objects than when we view scenes more passively. But the new research breaks new ground, mapping out a visual system amplifier that is directly activated by walking or running.
