A new model for how working memory gets you through the day

October 24, 2018
… pay more than $400.”) and regulate the higher frequency “gamma” waves that handle the new sensory information to be … the wave frequencies, in which beta would decline to allow gamma to increase when information needed to be stored or read out. Beta would then increase and gamma would die down when information could be discarded. …
