The effects of dietary supplementation with graded doses of raw white button mustrooms (A. bisporum) will be examined in the rats via age-sensitive motor behaviors and cognitive behaviors that are selective for reference and working memories. Following 12 weeks of dietary mushroom supplementation, aged rats will undergo behavioral testing with age-sensitive tests of psychomotor and cognitive behavior. These behaviors will be assessed using the Morris water maze and tests of motor funciton. All of these tests have been validated as being age sensitive (e.g., demonstrated a significant decline as a function of age). These studies should serve to elaborate further the beneficial effects of mushrooms on behavior in aging.
