Figure 1.
Despite a slower velocity, aged mice (open circles, n = 32) learned the task as well as adult mice (solid circles, n = 22). (A) During the 6 d of learning, aged mice swam more slowly than adult mice. (B) The distance needed to reach the platform decreased during the learning phase in both adult and aged mice. (Inset) The scheme of the maze. (Thick bar) Landmark position, (P) platform location.
