Relationship between P50 suppression and the cortical silent period
Bibliographic record
Abstract
Deficient inhibitory neurotransmission has been demonstrated in schizophrenia through electroencephalography (e.g. P50 suppression) and transcranial magnetic stimulation (e.g. short-interval cortical inhibition and the cortical silent period). It is not known whether these inhibitory paradigms are related despite evidence suggesting that both are coordinated through gamma-aminobutyric acid inhibitory neurotransmission. We explored the relationship between P50 suppression, short-interval cortical inhibition and the cortical silent period in 21 healthy participants using previously published methods. P50 suppression was significantly correlated with cortical silent period (r=-0.49, P=0.02) but not with short-interval cortical inhibition. As both P50 suppression and the cortical silent period have been linked to gamma-aminobutyric acidB receptor-mediated inhibitory neurotransmission, these data highlight the importance of this receptor subtype in the pathophysiology of schizophrenia.

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.
