Despite recent advances in brain research, understanding the various signals for pain and pain intensities\r\nin the brain cortex is still a complex task due to temporal and spatial variations of brain haemodynamics.\r\nIn this paper we have investigated pain based on cerebral hemodynamics via near-infrared spectroscopy\r\n(NIRS). This study presents a pain stimulation experiment that uses three acupuncture manipulation\r\ntechniques to safely induce pain in healthy subjects. Acupuncture pain response was presented and\r\nHaemodynamic pain signal analysis showed the presence of dominant channels and their relationship\r\namong surrounding channels, which contribute the further pain research area.
