David Marr (theoretical neuroscientist)

David Marr was a pioneering theoretical neuroscientist known for his work on understanding how the brain processes visual information. He proposed that the brain analyzes visual scenes through multiple levels of understanding: from raw light signals to detecting edges, shapes, and eventually recognizing objects. Marr emphasized breaking down complex brain functions into computational theories, layered processing steps, and neural mechanisms. His approach helped shape modern cognitive neuroscience, providing a framework for studying perception as a series of organized, logical stages, bridging biological implementation with computational explanation.
