At 95 weeks of age, progress through the maze during the first attempt followed a similar pattern to that seen at 83 weeks of age, with the most time being spent in zones C and E. On the second attempt, there was a reduction in the proportionate time spent in these zones, together with a statistically significant increase (P < 0.05) in the proportion of time spent in zones A and D, but this pattern change was not as marked as seen at 83 weeks of age. The proportion of time spent in zone C tended (P = 0.057) to decrease with each maze attempt in the Controls, so that they spent nearly equal proportions of time across all zones by attempt 3, but the GnRHa-Rec group still spent most of their time in zones C and E, even in attempt 3.
