Connections found between each meridian (heart, stomach, triple burner, etc.) & organ representation area of corresponding internal organs in each side of the cerebral cortex; release of common neurotransmitters and hormones unique to each meridian and corresponding acupuncture point & internal organ after acupuncture, electrical stimulation, mechanical stimulation (including shiatsu), soft laser stimulation or QI Gong.

Using the "Bi-Digital O-Ring Test Imaging Technique", the author has been able to accurately localize meridians and acupuncture points that correspond to specific internal organs and has found that most general patterns of meridians and the number of acupuncture points on each of the meridians of specific internal organs of the 12 main internal organs described in the literature of ancient Chinese medicine, are more or less correct, with the exception of some variations and inaccuracies. Each meridian of specific internal organs was found to be connected to the organ representation area in the cerebral cortex of specific internal organs. The acupuncture point has an area and occupies 3-dimensional space. It has a circular or slightly oval boundary with diameter in the range of 3 mm to 2.7 cm, although 6-12 mm are the most common diameters in human adults, with the exception of the area outside the corners of the nailbeds of the fingers and toes. Using the "Bi-Digital O-Ring Test Molecular Identification Method", the author also found that within the boundary of most acupuncture points and meridian lines (including Heart, Stomach, and Triple Burner) were high concentrations of neurotransmitters and hormones, including Acetylcholine, Methionine-Enkephalin, Beta-Endorphin, ACTH, Secretin, Cholecystokinin, Norepinephrine, Serotonin, and GABA. On all these meridian lines, in addition to the above neurotransmitters and hormones, Dopamine, Dynorphin 1-13, Prostaglandin E1 (PGE1) and VIP were found, but the latter do not usually exist within the boundary of the acupuncture point with the exception of the center midline of the acupuncture point where the meridian line is situated. Serotonin, Norepinephrine, and Cholecystokinin appeared in either one of the above 2 patterns, depending on the individual. Usually, no significant amounts of these neurotransmitters and hormones were found at the surrounding area outside of meridian and acupuncture points. However, the essential amino acid L-Tryptophan (which is a precursor of Serotonin), was usually found outside of the boundary of the acupuncture point and the meridian but not within the boundary of the acupuncture point and the meridian. Wherever Serotonin appeared, L-Tryptophan disappeared significantly and when the Serotonin disappeared, L-Tryptophan reappeared. In addition to the above common neurotransmitters and hormones, the Heart meridian had additional Atrial Natriuretic Peptide in both the meridian and its acupuncture points. Similarly, the Stomach meridian had additional Gastrin in both the meridian and its acupuncture points. Likewise,the Triple Burner meridian had additional Testosterone (in the male) and Estrogen (especially Estriol and Estradiol in the female.
