Study on the Performance of MRS of Certain Functional Parts of Brains of Elite Archers under Mental Imagery Generating State

This study aims to inaugurate a new method to study the senior function of human brain by contrast and analysis of the concentration value of NAA, Cho, Cr etc.in white matter of dorsolateral prefrontal cortex and the anterior cingulate cortex of 20 talented archers who have received a mental imagery training.The results show that:1) there is no distinct differences among the concentration values of NAA, Cho, Cr etc.in white matter of dorsolateral prefrontal cortex and the anterior cingulate cortex and the ratios of them between male and female.2) After the archers have received a mental imagery training, the concentration values of NAA, Cho and Cr in white matter of dorsolateral prefrontal cortex and the anterior cingulate cortex decrease sharply, and the brains response and metabolize quickly, which shows that the two parts have taken effect in this process and have helped to refresh the memory.
