 This article tries to summarize the PBWM (Prefrontal cortex Basal ganglia Working Memory) model in [[https://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Executive|the Executive chapter]] of [[https://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Main|the CCNBook]].  The PBWM model is further explained in O’Reilly & Frank’s paper: [[http://psych.colorado.edu/~oreilly/papers/OReillyFrank06_pbwm.pdf|Making Working Memory Work: A Computational Model of Learning in the Prefrontal Cortex and Basal Ganglia]], Neural Comput., 18(2) (2006).  This article tries to summarize the PBWM (Prefrontal cortex Basal ganglia Working Memory) model in [[https://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Executive|the Executive chapter]] of [[https://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Main|the CCNBook]].  The PBWM model is further explained in O’Reilly & Frank’s paper: [[http://psych.colorado.edu/~oreilly/papers/OReillyFrank06_pbwm.pdf|Making Working Memory Work: A Computational Model of Learning in the Prefrontal Cortex and Basal Ganglia]], Neural Comput., 18(2) (2006).
