Abstract
General anesthetics depress central nervous system excitability via a mechanism that probably involves effects on synaptic ion channels, but the fundamental molecular nature of the site where they act is unknown. Although the importance of hydrophobicity for general anesthetic drug potency has long been established, it remains uncertain whether these "nonspecific" drugs act on membrane proteins directly or by modification of the physical properties of the lipid membrane or the lipid-protein interface. We find that specific mutations in the acetylcholine receptor pore-forming M2 domains enhance the sensitivity of the receptor to the general anesthetics isoflurane, hexanol, and octanol, suggesting that these agents act by binding directly to a discrete protein site at or near these residues. The sensitivity of the receptor to block by general anesthetics increases with increased hydrophobicity of these residues, demonstrating that hydrophobic forces dominate the interaction of drugs with their protein site. Furthermore, octanol inhibits both wild-type and mutant nicotinic acetylcholine receptors preferentially after channel opening, which is consistent with a mechanism where drugs bind within the receptor's pore. Similar sites on postsynaptic ion channels in brain may represent general anesthetic targets for modulating consciousness.

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.
