Core Tip

Core tip: This study supports the “targeted convergence” hypothesis: Shu-acu point and Mu-acu point signals gather not only in spinal cord but also evince a ‘targeted convergence’ in brain stem and hypothalamus. We determined that the signals induced by electroacupuncture (EA) stimulation of gastric Shu and Mu points gather in the dorsal vagal complex (DVC) and paraventricular hypothalamic nucleus (PVN), increasing levels of gastrointestinal hormones and their receptors in the PVN and gastric antrum to regulate gastric motility. We hypothesize that EA at gastric Shu and Mu points regulates gastric motility, which may be achieved through the PVN-DVC-vagus-gastric pathway.
