Do dreams serve a purpose in the brain s function? Or are they part of the brain s nighttime functions?
A. In addition to helping our brains grow when we are young, researchers believe dreaming plays a role in memory by strengthening connections between certain areas of our brains, and by allowing other connections (less useful information) to be released and forgotten. REM sleep also plays a role in releasing certain hormones in the brain. Did you know that all anti-depressant drugs are effective because they dramatically reduce REM sleep? Scientists aren t sure exactly why reduced REM relieves depression but it does!
