Abnormal regional homogeneity (ReHo) in Congenital Amusia: a resting-state functional MRI study
Bibliographic record
Abstract
Abstract Congenital amusia (CA) is a disorder of pitch perception, a core function of the human auditory system. A total of seventeen amusics, fitting stringent criteria in Montreal Battery of Evaluation of Amusia (MBEA), and fourteen healthy controls participated in our study. Here, we aimed to characterize a local resting state functional measure, regional homogeneity (ReHo) to evaluate abnormal local consistency of the neurons spontaneous activity in CA group compared with the healthy control group. We focused on potential brain areas with significant differences between the two groups. The partial correlation analyses applied to ReHo values as well as scores of MBEA subtests. The CA group showed a significant decrease ReHo values in the left postcentral gyrus and left middle cingulum cortex when compared to controls. The ReHo values of those two significant regions were both positively correlated with MBEA scores. All in all, this study identified brain regions which were not discussed previously that may partly contribute to or be modulated by CA.

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.
