As the myelination progresses from the spinal root toward the periphery, the value of proximal conduction velocity would be higher than distal segment in developing nerve trunk.
All patients with clinical signs of spinal root deficit also underwent pre- and postoperative neurophysiological studies (see Neurophysiologic Evaluation).
It is well known that patients with primary headaches often report pain not only involving the frontal head innervated by the first (ophthalmic) division of the trigeminal nerve, but also involving the occipital region innervated by the greater occipital nerve (GON), a branch of the C2 spinal root [1-3].

Neurofibromatosis type 1 (NF1) is an inherited disorder characterized by formation of tumors (neurofibromas) involving nerve tissues in skin, subcutaneous tissues, cranial nerves, and spinal root nerves.
Localization helps in diagnosis: fasciculations can be generalised, in metabolic-toxic conditions, the benign fasciculation syndrome and degenerative disorders of anterior horn of spinal cord, as amyotrophic lateral sclerosis; segmental, as in syringomyelia; or focal, affecting the muscles controlled by a nerve or spinal root. When fasciculations are in a distribution that cannot be explained by plexus, root or nerve lesion amyotrophic lateral sclerosis (ALS) must be ruled out as soon as possible.
