Neuronal Group Selection Theory (NGST) is a neurodevelopmental theory proposed by neuroscientist Gerald Edelman in 1987.
It provides a framework explaining how the nervous system develops, organizes itself, and adapts to environmental influences through selective processes similar to Darwinian natural selection.
NGST is particularly influential in pediatric neurology and neurorehabilitation, explaining variability in developmental outcomes and the importance of early experience and environmental stimulation.
