Figure 9: Decreased contextual fear memory in aged WT mice.

Aged (16–20 months old) and young adult (2–4 months old) WT mice were subjected to one-footshock or three-footshock contextual fear conditioning. Memory was tested 24 h following training. Aged mice showed reduced contextual fear memory. n=11–13 per group. P<0.05 (post-hoc comparison). Data are expressed as mean±s.e.m.
