On average, 950 myelinated fiber profiles, 3300 points hitting the fibers and 1500 points hitting the myelin sheaths were counted per rat hemisphere.
He concluded that the human forebrain contains an average of 22 billion neurons, 157 trillion synapses, and 84,500 miles of myelinated fibers.
The present study was designed to identify changes in the diameters of the myelinated fibers and axons as well as the thickness of the myelin sheaths in the cerebellar white matter of control and chronic D-gal-treated mice.
This study shows that the ZDF rat, which displays oxidative-nitrosative stress, MNCV and SNCV deficit, thermal and mechanical hypoalgesia, small sensory nerve fiber degeneration, and a mild atrophy of large myelinated fibers, is a robust animal model for studying the manifestations and treatment of DPN in type 2 diabetes.
Sensory transmission in humans occurs through three primary afferent, nerve fiber types : heavily myelinated mechanical afferent pathways (A Beta fibers) that transmit non-noxious tactile sensations, small-diameter myelinated fibers (A Delta fibers) that transmit sharp pain, and small diameter unmyelinated fibers (C fibers) that transmit dull aching pain.
More than 25 years ago, I published a hypothesis (8) postulating that the delusions of passivity and external control may be caused by an abnormality in the corpus callosum--the largest white matter bundle in the brain, comprised of approximately 200 million myelinated fibers connecting homologous regions in the left and right cerebral hemispheres.
Due to the constant pain caused by FM, small, unmyelinated nerve fibers are activated more frequently than the larger myelinated fibers (9).
The evidence suggests that effects of spinal manipulative therapy is primarily neurophysiologic, most likely mediated by intense stimulation of large myelinated fibers in the capsular and/or periarticular tissues.
