“such supplements (strawberry, spinach, or blueberry at 14.8, 9.1, or 18.6 gm of dried aqueous extract per kilogram of diet, respectively) fed for 8 weeks to 19-month-old Fischer 344 rats”
Morris water maze testing
Rats were tested on the Morris water maze task to assess spatial learning and memory performance
Note: Testing conducted after 8 weeks of dietary supplementation to evaluate cognitive performance
