Afferent signals are sent from a nerve receptor into the brain while efferent signals are sent from the brain to the peripheral body.Visceral feelings and gut instincts are literally emotional intuitions transferred up to your brain via the vagus nerve. In fact, 80-90% of the nerve fibers in the vagus nerve are dedicated to communicating the state of your viscera up to your brain.The terms “afferent” and “efferent” typically refer to nerves that lead into or out of the brain. The Vagus Nerve Wanders EverywhereThe vagus nerve is constantly sending updated sensory information about the state of the body's organs 'upstream' to your brain via afferent nerves. This technique has provided a new method that is especially useful in assessing the small sensory pain fibers that are 'invisible' in nerve conduction studies.The team of scientists was led by Urs Meyer, a researcher in professor Wolfgang Langhans' group at ETH Zurich.The is titled, “Gut Afferents Differentially Modulate Innate Anxiety and Learned Fear” and was published in the Journal of.The Vagus Nerve Conveys Messages Between the Brain and Gut. The Cutaneous Neurology lab is one of labs that developed the technique of skin biopsies immunostained to see the small nerve fibers within the skin. The Nerve and Muscle Biopsy service performs more than 200 biopsies yearly and receives biopsies from other hospitals for processing, interpretation and review. The Electrophysiology lab is one of the foremost clinical and research groups in the world for electromyography (EMG), nerve conduction studies (NCV's), and specialized techniques such as single fiber recordings. The clinicians of the Peripheral Nerve Center have access to outstanding diagnostic laboratories.

We are committed to offering state-of-the-art neurological and neurosurgical care and work closely with colleagues from other disciplines to provide team-oriented, multi-disciplinary care.

This includes a holistic approach addressing the total well being of the patient. The peripheral nerve center strives to provide the best possible care to the patient and their families. The Center was founded to provide the highest quality care for peripheral nerve diseases, including surgical options, and to generate new understanding of the diagnosis and treatment of nerve diseases through research.įor more than twenty years, patients from all around the world have come to Johns Hopkins for care of their peripheral nerve problems. The Peripheral Nerve Center at Johns Hopkins has assembled a group of specialists that provide expertise in most nerve disorders, including diagnosis and both medical and surgical treatments.
