An internationally significant study of healthy twins, 65 years of age or older, has unlocked important clues about how genes influence the development of key grey matter structures, paving the way for a genetic blueprint of the human brain.
A team led by researchers from UNSW Medicine analysed the MRI scans of 322 individuals from the Older Australian Twins Study. The objective was to map the genetic relatedness (or heritability) of cortical and subcortical structures in their brains. These structures are responsible for functions ranging from memory and visual processing, to motor control.
