Fig 7. The influence of L. plantarum CCFM639 upon Al induced behavioral deficit (Morris water maze test).

(A) Comparison of escape latency to platform during five training days (acquisition test). The escape latency is the time it takes to find the hidden platform. Asterisks above the lines show significant differences to the other three groups (p < 0.05). (B) Comparison of numbers of crossing over platform site on the sixth day (retrieval test). Lowercase letters on the top of the bars show significant differences among the four groups (p < 0.05). (C) Comparison of the time and distance travelled in the target quadrant with other quadrants on the sixth day. Uppercase and lowercase letters on the top of the bars show significant differences among the four groups (p < 0.05). (D) The moving trajectory of each group in the acquisition and retrieval test, the first four trajectories are in acquisition test, and the next four trajectories are in 60s retrieval test. 639 = L.plantarum CCFM639.
