Abstract
The present study showed that lyophilised berries significantly enhanced short-term memory, but not long-term memory in the inhibitory avoidance task, and induced an increase in the number of crossings in the first exposure to the open field. However, treated rats did not present any improvement of memory retention in open field habituation. Additionally, prolonged treatment with lyophilised berries did not have any significant effects in the elevated plus-maze task. Another interesting finding was that lyophilised berries improved working memory in the radial maze, with significant differences observed during sessions 1-2 and 4, but did not alter reference memory in this task. These results suggest that lyophilised berries may be beneficial in the prevention of memory deficits, one of the symptoms related to AD, and corroborate previous findings showing that flavonoids present effects in several learning paradigms.
