grandmother cell

grandmother cell n. a neuron that is said to fire when a person recognizes a single individual. Editorial Note: This term is directly tied to a theory of neurology which posits that individual brain cells contain individual memories, as opposed to each memory being stored across a matrix of cells. Etymological Note: Jerome Lettvin is often credit with coining this term, but that has not been verified. (source: Double-Tongued Dictionary)
