(A) The cumulative distance traveled to reach the escape platform during spatial reversal learning training trials. All groups were equally proficient acquiring the reversal task, although the data approached significance for a main effect of group (see text for explanation). A comparison of the steepness of the learning curve between trials 1 and 2 indicates that the aged control and aged + fish oil (FO) groups were slower to learn the new location of the platform compared with the young group. (B) Reversal learning probe trial performance. Aged rats were significantly impaired compared with their young counterparts regardless of diet composition. *p < .05.
