Compared with Group C , glucose metabolism increased in bilateral superior temporal gyrus ( BA38 ) , right superior frontal gyrus ( BA9 ) , left cingulate gyrus ( BA24 ) , left culmen and pyramid of cerebellum , and right cerebellar tonsil of cerebellum in Group A. Compared with Group C , glucose metabolism increased in bilateral superior frontal gyrus ( BA6 , BA9 , BA10 ) , bilateral middle frontal gyrus ( BA6 , BA10 ) , left middle frontal gyrus ( BA4 ) , bilateral uncus of limbic lobe ( BA36 , BA38 ) , left cingulate gyrus ( BA24 , BA31 ) , left posterior cingulate gyrus ( BA30 ) , left precuneus ( BA7 ) , left inferior parietal lobule ( BA4 ) , and left lingual gyrus of occipital lobe ( BA18 ) in Group B. Compared with Group B , glucose metabolism increased in bilateral superior temporal gyrus ( BA22 , BA38 ) , right inferior frontal gyrus ( BA47 ) , left culmen and cerebellar tonsil of cerebellum in Group A. Activated encephalic regions of needling at Waiguan ( SJ5 ) were mainly dominated in the healthy side , bilateral superior temporal gyrus , and right inferior frontal gyrus .
