Abstract
Anesthetics have varying physiological effects, but most notably alter ion channel kinetics. Alfaxalone is a rapid induction and washout neuroactive anesthetic, which potentiates γ‐aminobutyric acid (GABA)‐activated GABA A receptor (GABA A ‐R) currents. This study aims to identify any long‐term effects of alfaxalone sedation on pyramidal neuron action potential and GABA A ‐R properties, to determine if its impact on neuronal function can be reversed in a sufficiently short timeframe to allow for same‐day electrophysiological studies in goldfish brain. The goldfish ( Carassius auratus ) is an anoxia‐tolerant vertebrate and is a useful model to study anoxia tolerance mechanisms. The results show that alfaxalone sedation did not significantly impact action potential properties. Additionally, the acute application of alfaxalone onto naive brain slices caused the potentiation of whole‐cell GABA A ‐R current decay time and area under the curve. Following whole‐animal sedation with alfaxalone, a 3‐h wash of brain slices in alfaxalone‐free saline, with saline exchanged every 30 min, was required to remove any potentiating impact of alfaxalone on GABA A ‐R whole‐cell currents. These results demonstrate that alfaxalone is an effective anesthetic for same‐day electrophysiological experiments with goldfish brain slices.

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 it
