cell assembly

a group of neurons that are repeatedly active at the same time and develop as a single functional unit, which may become active when any of its constituent neurons is stimulated. This enables, for example, a person to form a complete mental image of an object when only a portion is visible or to recall a memory from a partial cue. Cell assembly is influential in biological theories of learning and memory. [proposed in 1949 by Donald O. Hebb]
