Studies Show That Brain Cells Do Not Regenerate But Remain The Same Throughout

...this renewal ability. However, studies on apes and rodents have indicated that brain cells can reform in mammals after all – including man. One problem with these findings has been the research methodology, as the most common way of measuring the age of nerve cells is extremely complicated, especially in man...
