Cerebral cortex surface area (Grasby, 2020)

STUDY TITLE: The genetic architecture of the human cerebral cortex

SUMMARY: Identification of over 250 genetic loci associated with cortical surface area.

OVERVIEW: The cerebral cortex is the outer layer of the brain that is responsible for cognitive tasks such as perception, thought and memory. It is characterized by folds that increase its surface area. To identify genetic variants associated with human cortical surface area, this study combined genetic data with brain imaging data from over 50,000 individuals. The study discovered over 250 genetic regions, which collectively explain an estimated 34% of the heritability of cortical surface area. Many of the identified genetic variants are linked to genes in the Wnt signaling pathway, which are active by neural progenitor cells during fetal development. Moreover, the study found that cortical surface area is positively correlated with educational attainment and Parkinson’s disease and negatively correlated with attention deficit hyperactivity disorder, depression, and neuroticism.

DID YOU KNOW? Folds in the cerebral cortex of the brain allow a large number of neurons to be packed into a small space. This has enabled the development of advanced brain functions. [SOURCE]
