Key result
Anticipation of a hard task increased Dorsolateral Prefrontal Cortex (DLPFC) activity measured by fNIRS compared to an easy task.

fNIRS detects DLPFC activity during hard-task anticipation; leaves open clinical utility pending prospective validation.
Does anticipation of a hard mental task increase DLPFC activity compared to an easy task as measured by fNIRS?
This study validates fNIRS as an effective tool to measure DLPFC activity during the anticipation of mentally effortful tasks, offering a cost-effective alternative to fMRI.
Vassena et al. (2018) studied this question. Anticipation of a hard task vs. Anticipation of an easy task was evaluated on Dorsolateral Prefrontal Cortex (DLPFC) activity during the anticipation phase. Anticipation of a hard task increased Dorsolateral Prefrontal Cortex (DLPFC) activity measured by fNIRS compared to an easy task.
