New Links between Genes and Brain Sizes Identified
A team of researchers from the Universities of Bath and Lincoln, United Kingdom, identified new links between genes and brain size. This discovery opens a new direction for research to a better understanding of brain development and mental diseases.
Having compared genomes of 28 mammals with different sizes of neocortex, the brain region involved in higher cognitive processes like language and decision-making, the scientists have identified a number of gene families that can grow and contract through gene duplication and deletion that have expanded in line with the growth of the neocortex relative to the size of the brain.
The scientists hope that their discovery may provide new clues into what goes wrong in a number of mental health diseases, like dementia.
