Effects of Dopamine on Gonadotropin Release in Female Goldfish, Carassius auratus
Bibliographic record
Abstract
Intraperitoneal injections of dopamine (DA) or its agonist, apomorphine decreased and pimozide, a DA antagonist, increased serum gonadotropin (GtH) levels in normal female goldfish. Injection of DA into the third cranial ventricular did not alter serum GtH concentrations. Intraperitoneal injections of DA or apomorphine each reduced the highly elevated serum GtH levels caused by preoptic lesions which abolish an inhibitory hypothalamic influence on GtH release allowing prolonged spontaneous release of GtH. Intraperitoneal injections of DA or apomorphine blocked the stimulation of GtH release induced by injections of a luteinizing hormone-releasing hormone analogue. These results indicate that DA has GtH release-inhibitory activity by actions directly on gonadotrophs to inhibit spontaneous secretion of GtH, and by blocking the actions of the GtH-releasing hormone.

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.
