Sensor position on the prefrontal cortex region with respect to Fpz (International 10–20 system).

<p>Yellow dots: Sources, Blue dots: Detectors. Numbers indicate the loaction of the channels based on the source-detector pairs. The dotted squares indicate channel parinings.</p

Estimated marginal means of WM activation level across all tasks in different PFC regions.

Differences in activation between high performance (HP) and normal performance (NP) groups.

<p>Both auditory and visual NP groups showed higher activation in PFC compared to their high-performance cohorts in right DLPFC during visual (a) and left DLPFC and MPFC during auditory (b) tasks.</p

Differences between high performance and normal performance groups in visual and aural VARK scores.

<p>(a) during performance of visual task and (b) during performance of auditory task.</p
