Stanford explores new avenue for brain injury, paralysis research
..., Goldberg speculated that neurons had an internal clock that determined when they were destined to stop regenerating. To test his theory, Goldberg kept groups of isolated embryonic neurons alive in his laboratory until they were the same age as neurons in the 8-day-old rats.
