Psychological Isomorphism

Köhler's Gestalt hypothesis that psychological experiences have the same structural form as the underlying brain processes — a structural correspondence between perception and neural activity.

Isomorphism: the structure of perceptual experience mirrors the structure of underlying physiological brain processes — not in terms of elements, but in terms of dynamic organization and relations. The perceived Gestalt (organized whole) corresponds to an organized, holistic brain process. Contrasts with elementistic approaches that decompose experience and brain activity into isolated units. Shaped later neural holism and field theories of perception.
