Decoupling Measurements and Processes: On the Epiphenomenon Debate Surrounding Brain Oscillations in Field Potentials
Bibliographic record
Abstract
Various theories in neuroscience maintain that brain oscillations have an important role in neuronal computation, but opposing views claim that these macroscale dynamics are “exhaust fumes” of more relevant processes. Here, we argue that the question of whether oscillations are epiphenomenal is ill-defined and cannot be productively resolved without further refinement. Toward that end, we outline a conceptual framework that clarifies the dispute along two axes: first, we introduce a distinction between measurement and process to categorize the theoretical status of electrophysiology terms such as local field potentials and oscillations. Second, we consider the relationships between these disambiguated terms, evaluating based on experimental and computational evidence whether there exist causal or inferentially useful links between them. This decomposes the question of epiphenomenalism into a set of empirically tractable alternatives. Finally, we demarcate oscillations as a conceptually distinct entity where either processes or measurements exhibit periodic behavior, and we suggest that oscillatory processes orchestrate neural computation by implementing a temporal, spatial, and frequency syntax. Overall, our reframed evaluation supports the view that electric fields—oscillating or not—are causally relevant, and that their associated signals are informative. More broadly, we offer a vocabulary and starting point for scientific exchanges on the role and utility of brain signals and the biological processes they capture.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
