Working memory is the transient retention and manipulation of information that can then be used to make a selection among choices, i.e. a decision. I propose a unifying framework of neural dynamics that could underlie different key features of decision making (such as the speed-accuracy trade-off) and working memory (such as capacity, distractibility and overload). We developed spiking neural models that capture decisions and working memory independently or within the same network as a function of a single (cognitive) control parameter, which we propose to be distal network disinhibition. The predicted neural mechanisms are helpful in understanding canonical computations underlying a variety of cognitive process beyond decisions and working memory.</div></div><div><br></div><div> </div></div>
