At least a third of the approximately 20,000 different genes that make up the human genome are active (expressed) primarily in the brain. This is the highest proportion of genes expressed in any part of the body. These genes influence the development and function of the brain, and ultimately control how we move, think, feel, and behave. Combined with the effects of our environment, changes in these genes can also determine whether we are at risk for a particular disease and if we are, the course it might follow.
This Research Guide is an introduction to genes, how they work in the brain, and how genomic research is helping lead to new therapies for neurological disorders ... (view the Research Guide below for the full story).
