The Residual Impact of Alfaxalone on GABAA Receptors and on the Electrophysiological Properties of Goldfish Pyramidal Neurons
Bibliographic record
Abstract
Alfaxalone is a relatively new anesthetic authorized for use in Canada and my goal is to determine if its impact on neuronal function can be reversed in a sufficiently short timeframe to allow 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. Alfaxalone potentiates GABAA receptor currents, and this study aims to identify any long-term impact of whole-animal Alfaxalone sedation on action potential and GABAA receptor properties. I found that following whole-animal sedation with Alfaxalone, that a 3-hour wash of brain slices in Alfaxalone free saline, with saline exchanged every 30 minutes, was required to remove any impact of Alfaxalone on GABAA receptor whole cell currents. In addition, Alfaxalone sedation did not significantly impact action potential properties. These results demonstrate that Alfaxalone is an effective anaesthetic for same-day electrophysiological experiments with goldfish brain slices.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
