This shows the timeline during a single trial. During both Delayed Match to Sample (DMS) and Passive Viewing (PV) trials, some units in the LGN module are raised to a high value during S1 and S2. The time between the end of S2 and before the reset of the working memory circuit is when the model responds as to whether a match has occurred. The middle and bottom traces show the time course of the ATTS module that is activated during Delayed Match to Sample (DMS) trials but is kept at a low value during Passive Viewing (PV) trials. Multiple trials are concatenated to form an experiment run. The stimuli used in our simulations are shown in the top panel (a “T” and a “+”).
