Positive Emotions Associated With Touch
planetc1.com-news 
By Michael Dorausch, D.C.Researchers have discovered that specific nerves in the body appear to communicate to the brain the positive emotions associated with touch. That, according to a study published in the upcoming September issue of Nature: Neuroscience. An article related to the study appeared in yesterdays Reuters News. According to the article, researchers have discovered that specific nerves (C-fibers) may play a key role in communicating emotional information from the point of touch to the brain. The nerve fibers reportedly send "emotional aspects of touch to the brain." A brain scan along with functional MRI showed areas of a womans brain "processing emotional information" when researchers stroked her arm lightly using a paintbrush. Can stroking someone lightly trigger the parts of the brain that are involved in processing emotional information? Researchers hope to gather more information on this subject and a test is being conducted among a group of patients with spinal cord injuries. One researcher believes these nerve fibers "communicate feelings of well-being." I believe SPEARS technique involved a light stroking of the spine from occiput to sacrum in hopes of communicating emotional information to the brain. If you have data on this, please send it our way. Reuters:: Nerves Deliver Emotional Message of Touch
