(mem′ŏ-rē )

[L. memoria, the faculty of remembering, memory, recollection]

1. The mental registration, retention, and recollection of past experiences, sensations, or thoughts. This group of functions relies on the coordinated activities of the association regions of the cerebral cortex, specific sensory areas of the brain, subcortical centers, the hypothalamus, the midbrain, and a wide array of neurochemicals and neurotransmitters. Injury or damage to any of these regions of the brain (as by intoxication, stroke, atrophy, or infection) impairs the ability to incorporate new memories or recall and use earlier ones.
2. The capacity of the immune system to respond to antigens to which it has previously been exposed. Immunological memory depends on the activities of T and B lymphocytes, macrophages, major histocompatibility molecules, adhesion molecules, chemokines, and many other biochemicals.
