Unique Epigenetic Code Identified During Human Brain Development (1 of 2) (image) Salk Institute Share Print E-Mail Caption A new study by Salk researchers provides the first comprehensive maps of epigenomic changes in the brain known as "DNA methylation," a chemical modification of a cell's DNA that can act as an extra layer of information in the genome. The study provides clues as to how specific genes are regulated in fetal, juvenile and adult brain cells, and the findings form a critical foundation to explore whether changes in methylation patterns may be linked to human diseases, including psychiatric disorders.
