Two Solitudes: Wilder Penfield, Ewen Cameron, and the Search for a Better Lobotomy
Bibliographic record
Abstract
In the 1940s, Wilder Penfield carried out a series of experimental psychosurgeries with the psychiatrist D. Ewen Cameron. This article explores Penfield's brief foray into psychosurgery and uses this episode to re-examine the emergence of his surgical enterprise. Penfield's greatest achievement - the surgical treatment of epilepsy - grew from the same roots as psychosurgery, and the histories of these treatments overlap in surprising ways. Within the contexts of Rockefeller-funded neuropsychiatry and Adolf Meyer's psychobiology, Penfield's frontal lobe operations (including a key operation on his sister) played a crucial role in the development of lobotomy in the 1930s. The combination of ambiguous data and the desire to collaborate with a psychiatrist encouraged Penfield to try to develop a superior operation. However, unlike his collaboration with psychiatrists, Penfield's productive working relationship with psychologists encouraged him to abandon the experimental "gyrectomy" procedure. The story of Penfield's attempt to find a better lobotomy can help us to examine different forms of interdisciplinarity within biomedicine.

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.
