at what age is the human brain fully formed
Brain diagram. Credit: dwp.gov.uk. (PhysOrg.com) -- New research from the UK shows the brain continues to develop after childhood and puberty, and is not fully developed until people are well into their 30s and 40s. The findings contradict current theories that the brain matures much earlier.
Although the brain reaches its full adult weight by the age of 21, it continues to develop for several years. In fact, a study done by the National Institutes of Health found that the region of brain that inhibits risky behavior does not fully form until age 25. This is the final stage of brain development.
