Is brain damage always permanent?
There are numerous kinds of brain damage. The impact that brain damage has, and whether or not recovery is possible, depends to a large degree on the location and severity of the injury.
A concussion, for instance, usually refers to the brain bouncing around inside the skull, which results in tearing and bleeding.
The brain can make remarkably recovery from minor injuries, and most people who experience a brain injury do not suffer permanent disability.Helpful? 1 person found this helpful.
What do endorphins do?
Endorphins perform several functions, but their best-known one is acting as a painkiller and a reward, causing a feeling of euphoria. Endorphins lock onto cells called opioid receptors, blocking the transmission of pain signals. Everyone has different triggers for endorphins, but common stimuli are pain, food and sex.
