Abstract
The comparative method is widely used to understand brain-behaviour relationships in comparative psychology. Such studies have demonstrated functional relationships between the brain and behaviour as well as how the brain and behaviour evolve in concert with one another. Here, the authors illustrate with their data on tool use and cerebellar morphology in birds that such comparisons can be further extended to (a) relate the morphology of a brain region to a behaviour, and (b) provide insight into the function of an often overlooked brain region in comparative cognitive studies, the cerebellum. Their results indicate that tool-using species have a significantly more folded cerebellar cortex, but not a larger cerebellum than non-tool-using species. This marks the first demonstration of an empirical relationship between the folding of a neural structure and a cognitive behaviour and in so doing, provides critical insight into the neural basis of tool use and the role of the cerebellum in cognitive processes.

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
