Abstract
Alpha oscillations are a robust neurophysiological phenomenon associated with cortical suppression and synaptic input gating, functionally interpreted as a mechanism of selective attention. Here, we highlight known dissociations between alpha oscillations and selective attention that question the specificity of this interpretation. We postulate that the inconsistencies are accounted for when we consider alpha oscillations as a neurophysiological mechanism that tracks cortical excitability, but one that can be modulated by a multitude of factors that include but are not limited to selective attention and include bottom-up and top-down interactions, internal processes, and regulatory system influences on cortical excitability. Thus, reverse inference regarding the cognitive role of alpha modulations may depend on experimental context. Importantly, this perspective reiterates that there exists a significant need for research that disentangles the mechanistic bases of alpha oscillations across different cognitive phenomena.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
