CX3CR1 and ischemia: Analysis of behavioral performance in the cued learning test showed significant main effects of ischemia (F(3,36) = 7.82, P <0.05) and CX3CR1 (F(3,36) = 7.95, P <0.05) where both ischemic groups had increased mean swim latency and frequently took the indirect route to reach the goal compared to the sham control animals.
