Scientists want to autopsy the brain of Boston Marathon bombing suspect Tamerlan Tsarnaev, who boxed throughout his life.

Scientists are calling for an autopsy of one of the Boston Marathon bombing suspects to see if he had brain damage. Though brain damage probably didn't play a role in the bombings, it may have contributed to other personality changes, researchers say.

Tamerlan Tsarnaev, 26, may have suffered from a type of brain damage caused by repeated impacts called chronic traumatic encephalopathy, or CTE, researchers say. Scientists believe CTE can cause emotional instability and impulse control.

Tsarneev was a boxer for most of his life, and family members and peers described dramatic personality changes in recent years. Still, the cold-blooded, planned nature of the attacks makes it highly unlikely that brain injury played a role in the bombs, Boston University neurology professor Robert Stern told Boston.com.
