Overlooked cells might explain the human brain’s huge storage capacity

MIT researchers developed a new model of memory that includes critical contributions from astrocytes, a class of brain cells. Anne Trafton | MIT News Publication Date: May 27, 2025  Press Inquiries   The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout
