Several studies claim to link brain size, weight, volume or head circumference to intelligence, but no clear or consistent pattern has emerged. Research suggests that Einstein may have had extra gyri and that certain focal areas of this cortex were unusual. Brain Size Is Linked to a Gene.
What limits brain size
In comparison to nonhumans, a mouse brain, for example, has few gyri which explains why a mouse has limited cognitive ability. The size of the brain is a frequent topic of study within the fields of anatomy and evolution. Research has shown that lead kills neurons nerve cells, resulting in smaller brains.

This article explains the stepbystep process of installing and activating MonsterInsights on your WordPress website. Brain size can be measured by weight or by volume via MRI scans or by skull volume. The total computational power of the brain is limited by several factors, including the ability to propagate nerve impulses from one place in the brain to another. Intervening white matter tracts in larger brains may severely limit the long-term contribution of new neurons born close to, or in, the ventricular wall.
