In 1947, Donal Hebb took some rats home from his lab at McGill University. Hebb let these rats grow up and live in his kitchen, which was an enriched environment. What was the main morphological (physical) difference between neurons of the 'home' rats vs. the control rats in the laboratory? Larger somas and axons Bigger and longer action potentials More mitochondria in the cell body Greater dendritic branching
