Abstract
The indoleamme serotonin (5-hydroxytryptamine, 5-HT) was described in the central nervous system (CNS) more than 30 years ago (Amin et al., 1954; Bogdanski et al., 1956; De Robertis, 1964; Twarog and Page, 1953; Zieher and De Robertis, 1963) based on biochemical determinations of this amine in different brain regions. These studies were rapidly followed by the use of histofluorescent microscopy (Anden et al., 1965, 1966, 1967; Dahlstrom and Fuxe, 1964; Fuxe, 1965; Moore et al., 1978; Ungerstedt, 1971) and measurements of the activity of tryptophan hydroxylase and 5-HT uptake (Kuhar et al., 1972). This work was later complemented by anatomical descriptions of the now chemically identified neurotransmitter systems using radioautographic tracing techniques that take advantage of the uptake properties of the 5-HT system (Azmitia, 1978; Azmitia and Segal, 1978; Beaudet and Descarrres, 1981, Parent et al, 1981) as well as by the use of immunocytochemrcal methods with antibodies against 5-HT itself (Steinbusch, 1981, Steinbusch et al , 1978; Steinbusch and Nreuwenhuys, 1983).

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.
