Hypothesis-generating for EEG-hemodynamic links in attention; prospective validation needed before clinical or research adoption.
Anticipatory alpha lateralization predicts attentional selection biomarkers and correlates with hemodynamic activation in the visual cortex.
Zhao et al. (2019) studied this question.
