Evolutionary changes in telencephalon size affect both egocentric and allocentric spatial learning in guppies
Summary: An artificial selection experiment on guppies shows that enlargement of the telencephalon, relative to the rest of the brain, enhances performance in two distinct spatial learning strategies.
