Imaging of the brain was carried by means of the bi-digital-O-ring test (ORT) with tissue in each region using neurotransmitters.<br>Frontal lobe (Brodmann's area 11) starts around Hsinhui, runs oblique-extero-posteriorly in parallel to the bladder (GABA) meridian and arrives at or around the area above Tienchu.<br>Parietal lobe (Brodmann's area 4) starts from around Chienting, runs oblique-extero-posteriorly through the inner side of the frontal lobe (meridian) and arrives at or around the area above Tienchu.<br>Central gray indicates Paihui. Central gray runs from Paihui oblique-extero-anteriorly, intersects the bladder (GABA) meridian around Chengkuang (Tungtien in some cases), runs further oblique-extero-posteriorly, intersects the bladder meridian (serotonin), and runs all over the body.<br>Mesencephalon (tissue excised along the line including red nucleus) starts from around Chiangchien, runs oblique-entero-posteriorly, intersects the bladder meridian and arrives at or around Fengchin.<br>Occipital lobe (Brodmann's area 17) starts from the intermediate of Chiangchien and Naohu, ruus oblique-extero-posterioly, intersects the bladder meridian, and arrives at or around Fengchin.<br>Pons (tissue excised along the line including nucleus ceruleus) starts from around Naohu, and arrives at Fengchin in the same manner as noted with the occipital lobe.<br>Medulla (tissue excised along the line including inferior Olivary nucleus at the swollen part) starts from immediately below external occipital protuberance, and arrives at or around Fengchin in the same manner as noted with the occipital lobe. The upper half of this meridian point reacts with medulla, while the lower half of the same reacts with hippocampus.<br>Temporal lobe (Brodmann's area 21) starts from around Hsuanlu, runs through the temple, and arrives at or around Wanku, or in some cases joins to the bladder (serotonin).<br>Cerebellum (tissue excised along the line including dentate nucleus) starts from the Governor vessel meridian at a level of the second cerebral vertebra, and arrives at the level of the 4th cervical vertebra.<br>From the above it was suggested that meridians on the Governor vessel of the cephalocervical region, the meridian above Tienchu, Tienchu, and Fengchin are useful for treatment of diseases related to the central nerve system.
