SEATTLE: Scientists investigated the potential of B. longum 1714 and B. breve 1205 to change cognitive processes in adult male BALB/c mice.
The lab animals received daily supplements of B. longum 1714, B. breve 1205 or control for 11 weeks. The researchers subjected the animals to a series of cognitive tests starting at week 4.
Result showed that the B. longum 1714-fed mice performed significantly better than the others in an object recognition test, while the B. breve 1205-fed mice performed better than the control mice.
The researchers also subjected the mice to the Barnes maze, which measures spatial learning and memory, and found that the B. longum 1714-fed mice made fewer errors than the other animals, “suggesting better learning,” they said…
