There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

“Simultaneous Representation of Sensory and Mnemonic Information in Human Visual Cortex”
John Serences, Ph.D.

Navigating through complex environments requires keeping relevant information in mind, or in working memory, while simultaneously processing new sensory inputs. For example, when frantically looking for your car keys in the morning, you need to hold in mind an image of what your keys look like while you scan each object in your living room for a match. Feature selective responses in early visual cortex are thought to play a role in maintaining information in working memory. However, these areas also must process new sensory inputs as you search the visual scene, and processing new inputs may wipe out information that you are trying to remember. I will discuss a recent set of studies that demonstrate region-wide multiplexing abilities in early visual areas, with population-level response patterns in visual cortex simultaneously representing the contents of working memory concurrently with new sensory inputs.
