Changes at one level often lead, over a period of years, to multilevel spondylosis and/or stenosis. Dermatomal somatosensory evoked potentials (dseps) and computerized tomography/magnetic.
Somatosensory evoked potential (sep or ssep) is the electrical activity of the brain that results from the stimulation of touch. Sep tests measure that activity and are a useful, noninvasive means of assessing somatosensory system functioning.
This is technically more feasible in children or young people than in older persons, and in slender persons than in obese persons. Spinal recordings can be obtained with mixed nerve or sensory nerve stimulation, but not with dermatomal stimulation. Spinal cord trauma the scalp sepis absent in complete spinal cord injuries.
Dermatomes are areas of skin, and each communicates with the brain via a single nerve. Here, find out these changes can be long term or even permanent.

The dermatomal somatosensory evoked potential (d-sep) is a new method to quantitatively evaluate breast sensibility [6] in 1875, richard caton discovered evoked potentials [7] evoked potentials are the electrical activity produced by groups of neurons within the spinal cord, thalamus, brain stem or brain in response to an external stimulus.
Significant somatosensory evoked potential (ssep) changes were predominantly defined as those having an amplitude reduction of 50% and/or a latency increase by 10% from baseline. In some studies, complete disappearance of sensory evoked potential was also used.
Dermatomal somatosensory evoked potentials (dsseps) not only provide a neurophysiological readout comparable with conventional sseps but also provide an opportunity to track changes in sensory function corresponding to individual dermatomes (ie, a single spinal segment) above, at, and below the level of spinal cord injury (sci).

The somatosensory homunculus places the foot representation on the mesial surface of the postcentral gyrus followed by the representations of the lower leg and the thigh in superio-lateral direction. However, this strong homuncular organization contradicts the “dermatomal” organization of spinal nerves.
Somatosensory evoked potentials have been utilized as an intraoperative monitoring tool for over 30 years [3,4]. They are currently used either to assess the functional status of somatosensory pathways during surgical procedures which may affect peripheral nerve or plexus [11-17], spinal.
Nondermatomal somatosensory deficits (ndsds) are large sensory deficits not conforming to dermatomal/root territories, and no structural pathology accounts for them. They can be very mild or very dense, highly variable, or extremely fixed over time and may be very disabling. It is now accepted by mainstream pain science that they are the product of a central neurophysiological phenomenon.
