We also found that spatial memory seemed to be more affected at older ages, although strategies appeared to be altered at different moments in the elderly: allocentric strategy performance was intact from 62 to 74 years of age, but the egocentric strategy declined from 62 to 66 years old and continued to decline from 67 to 75 years old.

Here, we present additional findings in wild-type rats showing that contextual fear memory acquisition or extinction upregulates the RyR2 isoform, which when downregulated causes striking spatial memory defects [31].
Four T mazes were used to measure spatial memory, they were made of black and white acrylic, and they had four parts: the start white alley (36x13.5x17 cm), the black main corridor (39x13.5x17 cm) and two black arms (novel and other) which were perpendicular to the corridor (39x13.5x17 cm).
To examine the effects of herbal formulas comprising combinations of B, Y, P, and A on aging-related changes, the D-galactose-induced aging model was employed, which is based on the findings that chronic exposure to D-galactose not only causes shortened lifespan in Drosophila and housefly [28, 29], but also brings about neurodegeneration, increased oxidative stress in the brain, and spatial memory impairment [30, 31].
These data suggest a facilitation of extinction learning capacity, especially on shortterm spatial memory in old rats (Fig.

A UCLA study showed that adults age 60 and older who ate about 2.7 teaspoons of walnuts daily for three to six years scored higher on tests that measured story recall, response speed, sustained attention, and visual spatial memory.
Memory retention was assessed by means of the passive avoidance test and spatial memory was assessed using the Morris water maze test.
