Hi Bruce,

     I am sorry for this situation. 
     In the first way, there was an statistical difference in left hippocampus, but no difference in right hippocampus. In the second way, there was both no statistical difference in left or right  hippocampus. I don't know what causes this result. 
     Can you understand me this time?

Thanks,
Zheng
