Figure 3. Morris water maze testing. Morris water maze performance assessed as latency in seconds (A) and distance (B) to find the hidden platform over days 4 and 5 of testing for animals in control, GF1, GF2 and GF3 diet groups. After 16 weeks on the GF diets, the animals were subjected to Morris water maze. The final trial day is presented as seconds to find the hidden platform. Both males and females were used in the studies. Values are means, with their standard errors represented by vertical bars. N = 10 per group. *P<0.001.
