Synchronicity belies simplicity in short-term memory

Most of us draw on our visual recognition and short-term memory abilities many times a day and with relatively little fanfare, but these seemingly mundane activities have rather complex underpinnings within our brains. The tasks involve different, non-adjacent brain regions: short-term memory formation occurs in the lateral prefrontal cortex (PFC), and visual information processing primarily takes place in the occipital lobe, in the back part of the brain’s cerebral cortex. It is believed that these brain regions must interact during tasks requiring the use of short-term memories for visual recognition, but the nature and mechanism of their interaction is not well understood. Stefanie Liebe and Gregor Rainer (Max Planck Institute for Biological Cybernetics, Tuebingen, Germany) led a study to investigate the potential interaction between the brain areas.
