Arachidonic acid improves aged rats' spatial cognition

Fatty acids in the hippocampi were measured after the behavioral testing. There was no difference in AA composition in hippocampal phospholipids between the OA and OC groups. However, regression analysis conducted on AA composition and place task performance showed a significant correlation between these two parameters. The present study suggests that AA administration to aged animals can alleviate age-related deficits in spatial cognition.
