The peripheral portion of the nervous system involves the nerves that leave your brain and spinal cord and travel to the rest of your body. The peripheral nervous system carries sensory information (for instance, pain, pressure, heat and spatial awareness) to your brain. The peripheral nervous system also carries motor information from your brain and spinal cord back to the muscles of your body, including voluntary movement or involuntary function, such as breathing. There are several diseases that affect the peripheral nervous system and some are well suited to neurosurgical treatment, such as the surgical freeing of entrapped nerves. Allen H. Maniker, MD specializes in the surgical treatment of these disorders.
