Hubs of Brain Working Memory Circuit

Caption: A brain visual working memory circuit holds information in mind about what has just been seen. It represents the memory and distinguishes among objects via unique patterns of brain wave synchronization between neurons in the circuit. For example, two distant hubs in the circuit, one at the front of the brain (right circle) and the other at the rear side (left circle), showed varying amounts of synchrony in their brain waves, depending on what object a monkey was holding in memory. The coherence of synchronous activity between cells in these regions was plotted for different objects the monkey saw over several trials.
