Brain’s astrocytes play starring role in long-term memory

LA JOLLA—Star-shaped cells called astrocytes help the brain establish long-lasting memories, Salk researchers have discovered. The new work adds to a growing body of evidence that astrocytes, long considered to be merely supportive cells in the brain, may have more of a leading role. The study, published in the journal GLIA on July 26, 2019, could inform therapies for disorders in which long-term memory is impaired, such as traumatic brain injury or dementia.
