The historic view is that once brain cells are damaged or killed, they do not regenerate. Yet, research over the last 20 years is showing substantial evidence of cell regeneration, particularly in those under 40 year of age.

He says that it's actually called compensatory hyperplasia, and the cells simply grow to accommodate the decrease in function. When you cut part of the liver out, that part doesn't grow back. What got left behind will simply grow. You can tell the pieces apart, unlike the regeneration of the axolotl.. However, he noted, the liver is still an amazing organ in which as small as 25 per cent can heal into a healthy and complete liver.
