Baby neurons in adult brains are needed to maintain memory

Posted by in categories: biotech/medical, life extension, neuroscience

A quarter-century ago, researchers discovered that adults, not just developing infants, can generate new brain cells, a process called neurogenesis. But it’s still not clear what role these new neurons play in health or disease.

In a new mouse study, Columbia University researchers found that neurogenesis in adults is critical for maintaining that support working across the lifespan and chronic loss of adult neurogenesis causes , like that seen in age-related cognitive decline and Alzheimer’s disease in humans.

The study, “Adult-born neurons maintain hippocampal cholinergic inputs and support working memory during aging,” was published in July in the journal Molecular Psychiatry.
