| Research Abstract |
We examined the effect of a high-fat (HF) diet on learning and memory functions in clock-mutant mice (clock) comparing its wild mice (wild) by measuring passive avoidance test (PAT) and by using Morris Water Maze apparatus. In the results, not only clockmice fed on the control diet, but also wild female mice fed on the HF diet were impaired the retention for PAT. It became obvious that female mice, with respect to memory retention, are more susceptible to HF diet and that entrainment of the peripheral circadian rhythm is essential for maintenance of learning and memory functions in mice.
