Human experience is continuous, but psychologists believe, based on observations of people's behavior, that memories are divided by the brain into distinct events, a concept known as event segmentation. "One of the reasons we can't offer significant help for somebody who suffers from a memory disorder is that we don't know enough about how the memory system works," said Rutishauser, senior author of the study, adding that memory is foundational to us as human beings. As part of ongoing research into how memory works, Ueli Rutishauser, PhD, professor of Neurosurgery, Neurology, and Biomedical Sciences at Cedars-Sinai, and co-investigators looked at how brain cells react as memories are formed. The study, part of a multi-institutional BRAIN Initiative consortium funded by the National Institutes of Health and led by Cedars-Sinai, was published in the peer-reviewed journal Nature Neuroscience. The discovery provides new promise as a path toward development of novel treatments for memory disorders such as dementia and Alzheimer's disease. In a study led by Cedars-Sinai, researchers have discovered two types of brain cells that play a key role in dividing continuous human experience into distinct segments that can be recalled later.
