Neurophysiology (from Greek Ancient Greek is the historical stage in the development of the Greek language spanning across the Archaic , Classical (c. 5th–4th centuries BC), and Hellenistic (c. 3rd century BC–6th century AD) periods of ancient Greece and the ancient world. It is predated in the 2nd millennium BC by Mycenaean Greek. Its Hellenistic phase is known as Koine νεῦρον, neuron, "nerve"; φύσις, physis, "nature, origin"; and -λογία, -logia -logy is a suffix in English, found in words originally adapted from Greek words ending in -λογία . The earliest English examples were anglicizations of the French -logie, which was in turn inherited from the Latin -logia) is a part of physiology Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Physiology has traditionally been divided between plant physiology and animal and all living things physiology but the principles of physiology are universal, no matter what particular organism is being studied. For example, what is learned about. Neurophysiology is the study of nervous system The nervous system is a network of specialized cells that communicate information about an organism's surroundings and itself. It processes this information and causes reactions in other parts of the body. It is composed of neurons and other specialized cells called glial cells,, that aid in the function of the neurons. The nervous system is function. Primarily, it is connected with neurobiology Neurobiology is the study of cells of the nervous system and the organization of these cells into functional circuits that process information and mediate behavior. It is a subdiscipline of both biology and neuroscience. Neurobiology differs from neuroscience, a much broader field that is concerned with any scientific study of the nervous system, psychology Psychology is an academic and applied discipline involving the systematic, and often scientific, study of human/animal mental functions and behavior. Occasionally, in addition or opposition to employing the scientific method, it also relies on symbolic interpretation and critical analysis, although it often does so less prominently than other, neurology Neurology is a medical specialty dealing with disorders of the nervous system. Specifically, it deals with the diagnosis and treatment of all categories of disease involving the central, peripheral, and autonomic nervous systems, including their coverings, blood vessels, and all effector tissue, such as muscle. The corresponding surgical specialty, clinical neurophysiology In some countries it is a part of neurology or psychiatry, for example the United States and Germany. In others it is an autonomous speciality, such as Spain, Portugal, Italy, the United Kingdom, Finland, Sweden and Norway, electrophysiology Electrophysiology is the study of the electrical properties of biological cells and tissues. It involves measurements of voltage change or electric current on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and particularly, biophysical neurophysiology Mathematical biology is also called theoretical biology, and sometimes biomathematics. It includes at least four major subfields: biological mathematical modeling, relational biology/complex systems biology , bioinformatics and computational biomodeling/biocomputing. It is an interdisciplinary academic research field with a wide range of, ethology Ethology is the scientific study of animal behavior, and a sub-topic of zoology (not to be confused with ethnology, which compares and contrasts different human cultures), neuroanatomy Neuroanatomy is the study of the anatomical organization of the brain. In vertebrate animals, the routes that the myriad nerves take from the brain to the rest of the body , and the internal structure of the brain in particular, are both extremely elaborate. As a result, the study of neuroanatomy has developed into a discipline in itself, although, cognitive science Cognitive science may be concisely defined as the study of the nature of intelligence. It draws on multiple empirical disciplines, including psychology, philosophy, neuroscience, linguistics, anthropology, computer science, sociology and biology. The term cognitive science was coined by Christopher Longuet-Higgins in his 1973 commentary on the and other brain sciences.

What are Nerve Conducton Studies?
Q. I have an appointment to have nerve conduction studies at the Department of Neurophysiology and am uncertain as to what this will involve. Will these tests show the cause for unusual sensations in the limbs?
Asked by Paul E - Sun Feb 11 04:24:40 2007 - - 2 Answers - 0 Comments

A. A nerve conduction velocity test, also called a nerve conduction study, measures how quickly electrical impulses move along a nerve. It is often done at the same time as an electromyogram, in order to exclude or detect muscle disorders. A healthy nerve conducts signals with greater speed and strength than a damaged nerve. The speed of nerve conduction is influenced by the myelin sheath the insulating coating that surrounds the nerve. Most neuropathies are caused by damage to the nerve's axon rather than damage to the myelin sheath surrounding the nerve. The nerve conduction velocity test is used to distinguish between true nerve disorders (such as Charcot-Marie-Tooth disease) and conditions where muscles are affected by nerve injury (such [cont.]
