Research reveals that a greater volume of grey encephalic matter exists in the brain areas of the right parahippocampus

A study undertaken by researchers of the Universitat Jaume I of Castellon (UJI), the Universitat Autonoma of Barcelona (UAB) and the company Eresa reveals the existence of a different anatomy in small areas of the brain which could help explain why one same stimulus triggers anxiety in some people and not in others.
