| early-phase response | Prompt onset of symptoms following an antigenic stimulus. (05 Mar 2000) |
|---|---|
| early posttraumatic epilepsy | Seizures beginning within one week after severe head injury. (05 Mar 2000) |
| early reaction | Local or generalised response that begins within a few minutes to about an hour after exposure to an antigen to which the individual has been sensitised. See: skin test, wheal-and-erythema reaction. Synonym: early reaction. (05 Mar 2000) |
| early receptor potential | A voltage arising across the eye from a charge displacement within photoreceptor pigment, in response to an intense flash of light. (05 Mar 2000) |
| early region | <molecular biology> Part of a viral genome in which early genes genes that are transcribed and expressed early during infection of a cell are clustered. (18 Nov 1997) |
| early seral species | <plant biology> Shrubs, such as ceanothus, and hardwoods, usually in tree form, such as red alder, bitter cherry and big leaf maple. These species start growing in natural succession soon after a disturbance (fire or logging). (05 Dec 1998) |
| early stage breast cancer | <oncology> Cancer is confined to the breast and has not spread to other sites in the body. (16 Dec 1997) |

| absence seizure | <neurology> A type of seizure that in contrast to the grand mal seizure, are noted for their brevity and for the degree of loss of awareness (brief staring spell) accompanied by minimal motor manifestations. A common form of childhood epilepsy. (06 Oct 1997) |
| akinetic seizure | Seizure characterised by sudden loss of muscle tone. Synonym: akinetic seizure. (05 Mar 2000) |
| atonic seizure | Seizure characterised by sudden loss of muscle tone. Synonym: akinetic seizure. (05 Mar 2000) |
| atypical absence seizure | An absence seizure associated with an EEG pattern of irregular or slow spike and wave at less than 2.5 Hz or paroxysmal fast activity on an abnormally slow background EEG. (05 Mar 2000) |
| audiogenic seizure | A reflex seizure precipitated by loud noises, rare in humans. Audiogenic seizures in rodents are an animal model of epilepsy. (05 Mar 2000) |
| major motor seizure | A grand mal seizure or other convulsive seizure. (05 Mar 2000) |
| gelastic seizure | A seizure characterised by laughing. This seizure type is often accompanied by hypothalamic lesions, such as hamartomas. (05 Mar 2000) |
