| immunological memory | <immunology> The systems responsible for the situation where reactions to a second or subsequent exposure to an antigen are more extensive than those seen on first exposure (but See immunological tolerance. The memory is best explained by clonal expansion and persistence of such clones following the first exposure to antigen. (18 Nov 1997) |
|---|---|
| immunologic memory | <immunology> The ability to rapidly produce large quantities of specific immune cells after subsequent exposure to a previously encountered antigen. (09 Oct 1997) |
| temporary memory | <psychology> Temporary storage of information for a few seconds to hours, as opposed to long-term memory which refers to material stored for days, years, or a lifetime. (12 Dec 1998) |
| long-term memory | That phase of the memory process considered the permanent storehouse of information which has been registered, encoded, passed into the short-term memory, coded, rehearsed, and finally transferred and stored for future retrieval; material and information retained in LTM underlies cognitive abilities.

| amnesia, retrograde | Amnesia for events that occurred before the onset of amnesia. (12 Dec 1998) |
| retrograde | 1. Moving backward or against the usual direction of flow. 2. Degenerating, deteriorating or catabolic. Origin: L. Gradi = to step (18 Nov 1997) |
| retrograde amnesia | Amnesia in reference to events that occurred before the trauma or disease that caused the condition. (05 Mar 2000) |
| retrograde aortography | Aortography by the injection of contrast medium into the aorta through one of its branches, e.g., the brachial artery, in a direction against normal arterial blood flow. (05 Mar 2000) |
| retrograde axonal transport | <cell biology> The transport of vesicles from the synaptic region of an axon towards the cell body: involves the interaction of MAP1C with microtubules. (11 Jan 1998) |
| retrograde beat | A beat occurring as an electrical activation of a portion of a heart chamber cephalad to the chamber of origin, e.g., an atrial beat triggered by an impulse originating in the ventricle. (05 Mar 2000) |
| retrograde block | Impaired conduction backward from the ventricles or A-V node into the atria. (05 Mar 2000) |
| retrograde cardioplegia | Cardioplegia effected by delivery of solutions via the coronary veins. (05 Mar 2000) |
| retrograde chromatolysis | Synonym: central chromatolysis. (05 Mar 2000) |
| retrograde conduction | Conduction backward from the ventricles or from the A-V node into and through the atria. Synonym: retroconduction, ventriculoatrial conduction, V-A conduction. (05 Mar 2000) |
| retrograde degeneration | The series of changes in a neuron following the severing of its axon, including central chromatolysis with displacement of the nucleus. (12 Dec 1998) |
