Key result
Visual pre-cueing revealed a positive neurovascular coupling effect during target anticipation and a negative coupling effect during distractor anticipation in human adults.
Why the study?
Selective attention is thought to involve target enhancement and distractor inhibition processes, but the neurovascular couplings between electrophysiological and hemodynamic activities remain to be elucidated.
Population
Human adults
Comparison
Pre-cueing by the visual field of coming target vs distractor vs both

Supports dissociated attention mechanisms; leaves open clinical translation and therapeutic targeting.
Observational
The study provides neurovascular evidence for the dissociation of mechanisms of target enhancement and distractor inhibition during selective attention.
Zhao et al. (2021) reported an observational. Visual pre-cueing of target, distractor, or both was evaluated on Neurovascular coupling between alpha power and oxygenated hemoglobin signal. Visual pre-cueing revealed a positive neurovascular coupling effect during target anticipation and a negative coupling effect during distractor anticipation in human adults.
