To Your Brain, the World Is 2D | Science News | Scoop.it

By studying the neurons inside rat brains, British neuroscientist Kathryn Jeffery has concluded that mammals most likely collapse the world into a two-dimensional map when navigating and calculating distances. Jeffrey's team enticed rats to climb up a spiral staircase while collecting electrical recordings from single cells. "The firing pattern encoded very little in­formation about height. The finding adds evidence for the hypothesis that the brain keeps track of our location on a flat plane, which is defined by the way the body is oriented."
