Why the human brain matures slower than its primate relatives
The human brain is a fascinating and complex organ that supports numerous sophisticated behaviors and abilities that are observed in no other animal species. For centuries, scientists have been trying to understand what is ...
Alzheimer's disease can be reversed in animal models to achieve full neurological recovery
For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery. Despite billions of dollars spent on decades of research, ...
