Discovery: Reindeer's fascinating color-changing eyes
Description
Reindeer's noses may not glow red, but these cold-loving creatures have evolved the ability to change the color of their eyes to help them thrive in northern winters. A neuroscientist explains how he discovered that a part of the reindeer eye called the tapetum lucidum is perfectly adapted to the dim, blue in the Arctic.
Featuring Glen Jeffery, a professor of neuroscience at the Institute of Opthamology at University College London in the UK.
