Human Brain Study Sheds Light on How New Memories are Formed

Pisa1.jpg

In the first study of its kind, UCLA and United Kingdom researchers found that neurons in a specific brain region play a key role in rapidly forming memories about every day events, a finding that may result in a better understanding of memory loss and new methods to fight it in Alzheimer’s and other neurological diseases.
