Fig. 7: Gamma regression modeling of the time to find the exit across trials at D + 15 and D + 30 for the visual discrimination task.

Each animal is depicted by a point. Animals that failed this task are assigned the maximum value (300 s). The overlapping points inherited from these animals are melted in a larger dot proportional to their number, which is displayed inside. The curves and their 95% confidence intervals are built using mixed generalized models with a gamma distribution and a log link function. The DF and VF curves did not differ significantly from one another (p = 0.436 for D + 15 and p = 0. 305 for D + 30). n = 25 in each diet group and for each trial.
