Exemplary parameters of the animal behavior during five-day maze tests performed/repeated at the 9^th month of age.

<p>(A) the total time (seconds) spent in the maze before the reward was reached by the animal on day 1^st, 2^nd, 3^rd, 4^th, and 5^th, (B) the time of walking (seconds) to reach the reward, (C) the time of immobility (seconds), (D) the total walking distance (meters). Abbreviations: White and black graphs characterize control and high-fat high carbohydrate diet-treated animals, respectively. The graphs show median values (squares), 25–75% variability ranges (vertically arranged rectangles), and maximal and minimal values (whiskers). Decimal indexes located below the graphs indicate statistical significance of intergroup differences at a given maze test (Mann–Whitney U-test).
