Abstract
Tractography provides a powerful framework to reconstruct white matter pathways from diffusion magnetic resonance imaging (dMRI) but remains challenged by its inherent ambiguity and lack of direct biological specificity. This short communication summarizes the key points of a debate held at the 2024 Tract-Anat Retreat on the utility of MRI and non-MRI quantifiable neuroanatomical and functional parameters for improving tractography. During the discussion, concerns were raised about the availability of histological properties only on post-mortem tissues, the disparity in scale between MRI and other modalities and the additional costs (both in time and money) of such additional parameters. However, we identified several areas that enhance the anatomical accuracy of tractography including the potential value of histological priors, functional imaging constraints, and microstructural metrics in guiding or validating tract reconstructions. These perspectives underscore the need for multimodal frameworks that bridge imaging and biology, enabling tractography towards a more anatomically grounded representation of white matter organization.

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
