The role of glial cells – or cells that “glue” the neurons together – has traditionally been that of a house keeper, cooking up and serving food, cleaning up waste products, and holding everything in place. In recent years the role of glial cells has been expanded somewhat, which leads us to Einstein’s brain:
In 1985 scientists at the University of California in Berkeley published anatomical studies of slivers of Einstein’s brain after counting the different cells in the organ. They found the only difference between his brain and those of dead doctors was a greater ratio of glial cells to neurons.
“We know from animal studies that as you go from invertebrates to other animals and primates, as intelligence increases, so does the ratio of glial cells to neurons,” said Professor Volterra, whose study appears in the journal Nature Neuroscience.
So what are the glial cells doing?
The scientists said the cells provide energy for neural circuits and help build connections, leading to a more complex brain structure.

Ohh… yeah… this really is Einstein’s brain.
