(Medical Xpress)—A team of researchers working at the Norwegian University of Science and Technology has isolated the neurons in the rat brain that are responsible for monitoring speed as rats run, walk or stop moving around. ...
As everyone who has gotten up in the middle of the night to go to the bathroom knows, the brain maintains a sense of place and a basic ability to navigate that is independent of external clues from the eyes, ears and other ...
