| remote memory | Memory for events of long ago as opposed to recent events. (05 Mar 2000) |
|---|---|
| retrograde memory | Memory for that which occurred before an event such as a brain injury. (05 Mar 2000) |
| memory | Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory. (12 Dec 1998) |
| memory cell | <immunology> Cells of the immune system that do not respond immediately when it first encounters an antigen but facilitates the more rapid secondary response when the antigen is encountered on a subsequent occasion. The long lasting immune memory is humoral and resides in B-cells, although it appears that persistence of the antigen may be essential. T-cell memory is shorter. (14 Oct 1997) |
| memory disorder | Disturbances in registering an impression, in the retention of an acquired impression or in the recall of an impression. (12 Dec 1998) |
| memory loop | An electronic device for retrieving data that had been stored and/or displayed upon the oscilloscope at an earlier time; used for reviewing electrical events immediately preceding a specific disturbance. (05 Mar 2000) |
| memory span | The maximum number of items recalled after a single presentation (auditory or visual). (05 Mar 2000) |
| memory T-cell | A T-cell that bears receptors for a specific foreign antigen encountered during a prior infection or vaccination. After an infection or a vaccination, some of the T-cells that participated in the response remain as memory T-cells, which can rapidly mobilize and clone themselves should the same antigen be re-encountered during a second infection at a later time. (09 Oct 1997) |
| memory trace | See: engram. (05 Mar 2000) |
| selective memory | <psychology> Reception or retrieval of only some of the events in an experience. (05 Mar 2000) |
| senile memory | Memory that is good for remote events, often in contrast to current events; characteristically seen in aged or demented persons. (05 Mar 2000) |
| short-term 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) |
| subconscious memory | Information not immediately available for recall. (05 Mar 2000) |
| 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) |
