In neuroscience, nerve conduction velocity (CV) is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include age, sex, and various medical conditions.
The most widely accepted model of an adult NSC is a radial, glial fibrillary acidic protein-positive cell. Quiescent stem cells are Type B that are able to remain in the quiescent state due to the renewable tissue provided by the specific niches composed of blood vessels, astrocytes, microglia , ependymal cells, and extracellular matrix present ...
A nerve conduction study (NCS) is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body.
A few common uses are determining whether a muscle is active or inactive during movement (onset of activity), assessing the velocity of nerve conduction, and the amount of force generated during movement. EMGs are the basis for nerve conduction studies which measure the electrical conduction velocity and other characteristics of nerves in the ...
Or, it can form a functional network that serves a certain function and modeled accordingly (Honey, C. J., Kotter, R., Breakspear, R., & Sporns, O. (2007), [8] Arbib, M. A. (2007) [7]). A third way is to hypothesize a theory of the functioning of the biological components of the neural system by a mathematical model, in the form of a set of ...
Measurement of chronaxie and rheobase for these diseased nerves has concluded that electrophysiologically, a patient with demyelinating (Type I) CMT demonstrates slow nerve conduction velocity, frequently accompanied by reduced amplitudes of motor and sensory action potentials; moreover, axonal (Type II) CMT can be attributed to impaired ...
