  • Electroencephalogram : A graphical record of the electrical activity of the brain.
  • Electromyography : Record of electrical activity in the muscle; recording the action potential in a muscle when the muscle contracts.
  • Electrophysiology : Study of electrochemical phenomena occurring in cells of living organisms and in particular, in neurons and muscular fibers.
  • Encephalitis : Inflammation of the encephalon.
  • Encephalon : The brain (encephalon): that part of the central nervous system that includes all the higher nervous centres that are enclosed within the skull (cerebrum, cerebellum, spinal bulb (medulla oblongata).
  • Encephalopathy : Any disease of the encephalon.
  • Enzyme : Very important protein in the body that catalyses specific chemical reactions. Many enzymes are necessary to perform even the simplest task such as the transformation of the sugar in the food we eat into the carbon dioxide we exhale. A missing or altered enzyme can cause serious problems.
  • Erucic acid : Monounsaturated fatty acid with 22 carbon atoms.
  • Erythrocyte : Red blood cell, responsible for carrying oxygen to body tissues (and carbon dioxide away).
  • Etiology : Study of the causes and factors of a disease.
  • Evoked potentials : Refers to the electrical signal produced by the nervous system in response to an external (sound, light) or internal (decision making, motor preparation) stimulation.
  • Ex vivo : Used in gene therapy, they represent in vitro cell cultures from cells harvested from the patient that are treated (with vectors) and reinfused to the same patient, avoiding any risk of rejection.
  • Exogenous : Originating from outside of a given organism.
  • Exon : Sequence of gene that codes a protein.
