Working Memory  A new study by researchers at UC Davis shows how our very short-term "working memory," which allows the brain to stitch together sensory information, operates. Today on Insight, Professor Steven Luck explains how the system retains a limited number of high-resolution images for a few seconds, rather than a wider range of fuzzier impressions.
