Chronic treatment with methylene blue has moderate effect in behavior. (A) Experimental design, n = 10. (B) Percent of time spent in each quadrant during the probe trial of MWM (F(15,144) = 8.781, p < 0.0001). MB rTg4510 recognize target versus opposite quadrant (F(3,36) = 3.38, p = 0.0286), *p < 0.05. (C) Search strategy imaging using a camera tracking system.
