Enhancement of maze learning in old C57BL/6 mice by dietary lecithin

Maze learning was studied in young and old C57BL/6 mice. One group of old animals was fed lecithin (supplemented with vitamin E). A second group of old mice and the young mice received standard laboratory mouse chow. The mice were tested on a three-choice-point maze. Young mice learned the maze significantly more easily than either group of old mice. Learning in the lecithin-fed old mice was significantly better than in the control group on a standard diet.
