Communication Between Brain Regions During Working Memory

BrainPost, 24 September 2019

Working memory refers to the temporary storage and manipulation of information. There is a wide-ranging network throughout our brain involving frontal and parietal regions that are responsible for working memory tasks. However, it is not known how the parietal brain regions can communicate with distant prefrontal brain regions (involved in cognitive control) in situations where a high level of cognitive function is required. Evidence from animal studies suggests that theta oscillations from the hippocampus—a pattern where neurons fire between five and 12 times per second—may play a role in working memory. Read more.
