Abstract

fetched live from OpenAlex

The hypothalamus (Fig. 1) embodies a group of nuclei that form the floor and ventrolateral walls of the triangular-shaped third ventricle. A thin membrane called the lamina terminalis forms the anterior wall of this compartment and contains osmoreceptor cells in a structure known as the organum vasculosum. The subfornical organ (SFO) also contains osmoreceptors. The organum vasculosum of the lamina terminalis (OVLT), the SFO, and the pituitary gland lack a blood-brain barrier. The supraoptic nucleus lies just dorsal to the optic chiasm and approx 2 mm from the third ventricle. The para-ventricular nucleus lies closer to the thalamus in the suprachiasmatic portion of the hypothalamus, but it borders on the third ventricular space. These well-defined nuclei contain the majority of the large neuroendocrine cell bodies, known as the magnocellular or neurosecretory cells, that manufacture arginine vasopressin (AVP) and oxytocin (OT). The neurohypophysis consists of ( 1 ) a set of hypothalamic nuclei, the supraoptic and paraventricular nuclei, which house the pericarya of the magnocellular neurons; ( 2 ) the axonal processes of the magnocellular neurons that form the supraoptical hypophyseal tract; and, ( 3 ) the neurosecretory material of these neurons, which is carried on to the posterior pituitary gland (Fig. 1). These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
