Memory research has shown that higher order brain regions such as the frontal lobes buzz madly when monkeys (and people) remember something briefly. But a new study in monkeys, which appears on page 120, is the first to show that even the lowest level, workaday region of the visual cortex also hums with anticipation while maintaining a memory. The researchers suggest that this part of the brain holds on to a simple sensation that helps guide more sophisticated parts of the memory system.
