A [[BrainStreamPlugIns|imported] table (StimDisplay in speller_common) is used to define all actions related to stimulus presentation. You can see the reference to this imported table in the 9th row of the main Actions table: '@speller_common.edt StimDisplay'. The imported table is shown below:

When the sequence is initialized, the epoch counter is increased by 1 and the speller grid is shown. Immediately afterwards, the highlightGrid function is executed. This function determines the number of the current stimulus (stimCode) and the corresponding grid (curStim), displays the correct image on the screen and inserts the marker highlightOn. After 0.05 seconds, the non-highlighted grid is shown. Another 0.05 seconds later, a decision is made whether to show another stimulus or end the sequence.
