Working memory
The Miller Lab has also mounted evidence for an update to the oldest and most fundamental neural model of cognition: Working memory. For the past 50 years, working memory has been thought to rely on cortical neurons that fire continuous impulses that keep thoughts “online”.  New work from the Miller lab has revealed more complex dynamics.  The impulses fire sparsely and interact with brain waves of different frequencies.   Higher frequency brain waves carry the contents of working memory while lower frequency brain waves act as control signals that gate access to and clear out working memory.
