Pathological Crying Caused by High-Frequency Stimulation in the Region of the Caudal Internal Capsule
Bibliographic record
Abstract
BACKGROUND: Pathological crying has been rarely reported after deep brain stimulation. The exact neural substrate is unknown, but it is often assumed that pathological crying and the pseudobulbar syndrome result from disturbances of a common neural pathway. DESIGN: Case report. SETTING: Tertiary referral center for neurosurgery. Patient A 48-year-old woman with advanced Parkinson disease who received bilateral implantation of deep brain stimulators in her subthalamic nuclei. RESULTS: Stimulation in the region of the caudal internal capsule resulted in pathological crying but no other features of pseudobulbar palsy. CONCLUSIONS: At least 1 of the pathways controlling crying passes through the region of the caudal internal capsule, and this pathway is distinct from those involved with laughter and nonemotional facial movements. Moreover, different stimulation frequencies may elicit either crying or anxiety but not both.

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.
