Discussion

Observational analysis shows that higher alpha oscillations correlate with quicker responses, implying greater task efficiency.

Increased baseline alpha power is linked to faster visual search responses.
Using a General Linear Model, we found no practice effects influencing this link.
Magnetoencephalography tracked cortical excitability and alpha oscillations during tasks.
Current findings call into question the traditional role of alpha in reducing visual processing.

Duecker et al. (2025) studied this question.
