Performances in a T-maze test. Ten rats in each group fed control diet (black bar), perilla seed diet (white bar), or perilla oil diet (gray bar) for 3 weeks (A) and 3 months (B) were trained until they reach the goal box 6 times consecutively and the numbers of errors they made were counted in each training section. Likewise, after the three training sessions for two weeks, actual tests were given with a reversed goal box at the T-maze (C). The number of trials before reaching the goal box 6 consecutive times were significantly reduced (*, p<0.05) in rats fed perilla or perilla oil diet.
