Another article on Einstein's brain with another version of the study results:

The autopsy revealed that Einstein’s brain was smaller than average, and the analyses showed the normal changes that happen with aging. Nothing more at the time was analyzed and the brain fragments were stored. Decades later, researchers asked Harvey for samples and noticed some unusual features while analyzing them.

In 1985, they showed that two parts of his brain contained an unusually large number of glia for every neuron. Another study showed that the parietal lobe lacks a furrow and operculum. This missing furrow might have enhanced the connections in this region, which is involved in the visual/spatial functions and mathematical skills like arithmetic.

Many of the photos were taken from unusual angles, and show structures not visible in photos that were analyzed previously. The most striking observation was the complexity and pattern of convolutions on certain parts of the cerebral cortex, especially in the prefrontal cortex and also the parietal lobes and visual cortex.

The prefrontal cortex is important for abstract thinking. The complex pattern of convolutions probably gave the region an unusual surface area, which might have contributed to his remarkable thought processes.

There was also an unusual feature in the right somatosensory cortex, which receives sensory information from the body. In this part, Einstein’s brain is expanded, which might have contributed to this accomplished violin playing. (my bold...no surprise to us)

According to Sandra Witelson, a behavioral neuroscientist at McMaster University in Hamilton, Canada, who discovered that the parietal operculum is missing from Einstein’s brain, the study’s biggest contribution may be in encouraging further studies. “It makes clear the location and accessibility of photographs and slides of Einstein’s brain,” she says.

Comment: Same point. His brain was unique as he was
