(A) CBP{HAT‒}/Tg-ON mice and control wt littermates showed the same freezing in tests of contextual and cued fear conditioning after 24 hr and 3 week delays.
(B–D) An open field activity test (see Experimental Procedures) showed that time in center (B), average velocity (C), and locomotor activity (D) were normal in CBP{HAT‒}/TgOn mice.
(E) Weights of CBP{HAT‒}/Tg-ON mice were the same as wt littermates.
