| 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.

| screen memory | In psychoanalysis, a consciously tolerable memory that unwittingly serves as a cover for another associated memory which would be emotionally painful if recalled. (05 Mar 2000) |
| selective memory | <psychology> Reception or retrieval of only some of the events in an experience. (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) |
| 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.

| association learning | The principle that items experienced together enter into a connection, so that one tends to reinstate the other. (12 Dec 1998) |
| avoidance learning | A response to a cue that is instrumental in avoiding a noxious experience. (12 Dec 1998) |
| machine learning | This is the study of how to create computers that will learn from experience and modify their activity based on that learning (as opposed to traditional computers whose activity will not change unless the programmer explicitly changes it). This discipline is a sub-set of Artificial Intelligence. (09 Oct 1997) |
| paired-associate learning | Learning in which the subject must respond with one word or syllable when presented with another word or syllable. (12 Dec 1998) |
