Abstract

fetched live from OpenAlex

BackgroundYou may not be aware of it, but your brain is orchestrating a complex ballet of activity while reading this sentence.Whether it is following a dot or reading a sentence; the brain is evaluating input and sending motoric output to perform optimally/efficiently.We can measure this flurry of activity using functional Magnetic Resonance Imaging (fMRI).Traditional fMRI analysis emphasizes what regions are "activated/deactivated" during a task, but it does not provide information about which regions are acting in synchrony or are being segregated.Knowing the synchronous/segregated brain regions during a task gives insights on the potential organization of the brain.NiBetaSeries seeks to provide information about the organization of the brain by correlating activation/deactivation patterns between brain regions during a task.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
