Cerebral cortex thickness (Grasby, 2020)

STUDY TITLE: The genetic architecture of the human cerebral cortex

SUMMARY: Identification of 27 genetic regions associated with cortical thickness.

OVERVIEW: The cerebral cortex is the outer layer of the brain that is responsible for cognitive tasks such as perception, thought, and memory. The thick cortex of the human brain is believed to have evolved to fulfill these functions. To identify genetic variants associated with cortical thickness, this study combined genetic data with brain imaging data from over 50,000 individuals. The study identified 27 genetic regions, which explain an estimated 26% of the heritability of cortical thickness. These regions are near genes that encode laminin receptors which are implicated in neuronal cell differentiation and migration.

DID YOU KNOW? “Thickheaded” is a misnomer. Although “thickheadedness” typically refers to a person who is not intelligent, some neuroimaging studies indicate that intelligence is positively correlated with cortical thickness during early childhood. [SOURCE]
