Abstract: Working memory is the sketchpad of consciousness, the fundamental mechanism the brain uses to gain volitional control over its thoughts and actions. For the past 50 years, working memory has been thought to rely on cortical neurons that fire continuous impulses that keep thoughts “online”. However, new work from our lab has revealed more complex dynamics. The impulses fire sparsely and interact with brain rhythms of different frequencies. Higher frequency gamma (less than 35 Hz) rhythms help carry the contents of working memory while lower frequency alpha/beta (~8-30 Hz) rhythms act as control signals that gate access to and clear out working memory. In other words, a rhythmic dance between brain rhythms may underlie your ability to control your own thoughts.

What kind of impact does working memory have on bias? My gut instinct says a lot.
hellll yeah
WMI in the 160+ range. I did not understand the video. All I know is that my mind seems to summon everything related automatically, and can feel how it's going to work before it happens. I don't have good "control" over my thoughts but I have a ton of freedom when I start thinking, using tools and techniques that I can't understand. Can't really be explained because it seems to exist on another plane. Really annoying, I wish science had progressed more in these areas.
Very confusing comment.
