n. In Hebbian theory, refers to a group of neurons organized as a single, functional unit. Through synaptic plasticity, the stimulation of a constituent neuron results in the simultaneous activation of the entire group. This explains how brain neurons adapt quickly to learning and association. Introduced by Canadian psychologist Donald Hebb in 1949.
CELL ASSEMBLY: “Strengthened at its neuronal synapses by cell assembly, the human brain is able to recall memories and complete images even when the stimulus is partial.”
