More evidence in support of the working memory model has been found in a study investigating the brain activity involved in retaining different aspects of a visual image for short periods of time. The research by John T. Serences from the University of California, San Diego, Edward F. Ester, Edward K. Vogel and Edward Awh from the University of Oregon shows that participants actively choose which parts of the visual information to hold in working memory and this information is stored in the activity of specific areas of the visual cortex.
