Recall a phone number or directions just recited and your brain will be actively communicating across many regions. It is thought that working memory relies on interactions between these regions, but how these brain areas interact and properly represent memory has remained a mystery.
At Baylor College of Medicine, Dr. Nuo Li, assistant professor of neuroscience and a McNair Scholar, and his colleagues investigated the nature of the communication between brain regions involved in working memory and found evidence that a modular network organization is critical for persistent neural activity.
How brain regions communicate
Li and his colleagues were able to see that each hemisphere of the brain has a separate representation of a memory. However, the hemispheres are tightly coordinated on a moment-to-moment basis, resulting in highly coherent information across them during working…
