Famed neuroscientist Marian Diamond, who studied Einstein’s brain, dies at 90

Marian Cleeves Diamond, a neuroscientist who studied Albert Einstein’s brain and was one of the first to show that the brain can improve with enrichment, has died.

The University of California, Berkeley, where Diamond was a professor emeriti of integrative biology, confirmed Diamond died July 25 at her home in Oakland, California.

She was 90.

In 1984, after receiving four blocks of the preserved brain of Einstein, she found that it had more support cells than average.

In her work with rats, she showed that an enriched environment — toys and companions — changed the anatomy of the brain.

She found that the brains of all animals, including humans, benefit from an enriched environment, and that impoverished environments can lower the capacity to learn.
