- 1 Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.  Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.

Excitotoxicity Excitotoxicity is the pathological process by which nerve cells are damaged or killed by excessive stimulation by neurotransmitters such as glutamate and similar substances. This occurs when receptors for the excitatory neurotransmitter glutamate (glutamate receptors) such as the NMDA receptor and AMPA receptor are overactivated by glutamatergic storm. Excitotoxins like NMDA and kainic acid which bind to these receptors, as well as pathologically high levels of glutamate, can cause excitotoxicity by allowing high levels of calcium ions (Ca 2+) to enter the cell.

excitatory postsynaptic potential The change in potential that is produced in the membrane of the next neuron when an impulse that has an excitatory influence arrives at the synapse; it is a local change in the direction of depolarization; summation of these potentials can lead to discharge of an impulse by the neuron. 1  Facebook.

exciton Exciton. a quasiparticle that represents an electronic excitation in a dielectric or a semiconductor. Excitons propagate through a crystal and are not associated with the transfer of electric charge or of mass.avydov splitting has been observed experimentally in a number of molecular crystals, such as naphthalene, anthracene, and benzene. In semiconductors, an exciton is a hydrogen-like bound state consisting of a conduction electron and a hole.

What is Dilation? - Definition & Meaning Dilation. The word dilation, in terms of human physiology, means to 'relax, open, or widen.' This is usually used in structures where materials are allowed to pass. Dilation is an autonomic process, which means you cannot consciously control it.nstructor: John Williams. Dilation is a key factor in regulating body processes. In this lesson, you will learn the definition of dilation, the purpose of it, and examples of its use in the body.
