Before the age of GPS, humans had to orient themselves without on-screen arrows pointing down an exact street, but rather, by memorizing landmarks and using learned relationships among time, speed and distance. They had to know, for instance, that 10 minutes of brisk walking might equate to half a mile traveled. A new Johns Hopkins study found that rats' ability to recalibrate these learned relationships is ever-evolving, moment-by-moment.... SCIENCE DAILY · 7 days
