Fig. 5A depicts the mean traverse times at the end of training (‘Trained < 1min’), and 4 weeks later when performance was assessed in the same maze (‘Long-term memory’) and in a novel maze design (‘Novel maze’). There were no effects of treatment on the number of attempts required to complete the training (Controls 6.6 ± 0.8; GnRHa-Rec 7.1 ± 0.9 attempts) or traverse times at the end of training. Compared to traverse times at the end of training, all animals took significantly (P < 0.001) longer to traverse the maze during long-term memory assessment, and GnRHa-treatment significantly exaggerated this effect (Treatment P = 0.041, Treatment × Time P = 0.041), as GnRH-Rec and Control animals were 2-fold and 1.3-fold slower, respectively.
