[The Legacy of Wilder Penfield: Cortical Mapping, Epilepsy Surgery, and the Montreal Procedure].
Bibliographic record
Abstract
Wilder Penfield (1891-1976) was a Canadian neurosurgeon whose pioneering work left a lasting mark on neuroscience and epilepsy surgery. He advanced knowledge of cortical localization by electrically stimulating the brain under local anesthesia, allowing patients to report sensations and movements. From these observations, he created the famous "homunculus," a functional map of motor and sensory areas. Penfield also developed the Montreal Procedure, a groundbreaking surgical approach for intractable epilepsy. By stimulating the cortex during awake operations, he identified and preserved critical regions for speech and movement while safely removing epileptic foci. His studies also revealed that cortical stimulation could evoke vivid memories and experiences, contributing to research on memory and consciousness. In 1934, Penfield founded the Montreal Neurological Institute (MNI), the first center to integrate clinical care, research, and education in neuroscience. This interdisciplinary model fostered collaboration among neurosurgeons, neurologists, psychologists, and basic scientists, becoming the prototype for modern neuroscience institutes. Through his surgical innovations, scientific insights, and commitment to education, Penfield trained generations of specialists and shaped the field of translational medicine. His legacy continues to influence epilepsy surgery, cortical mapping, and the study of brain-mind relationships.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
