Ultrastructural Changes in the Preoptic Nucleus of the Rabbit Following Coitus
Bibliographic record
Abstract
The effects of coitus on the ultrastructure of neurons in the preoptic nucleus of the rabbit were studied. The ultrastructural changes observed first became apparent in large neurons located near capillaries, 1 h after coitus. More pronounced changes were observed in neurons removed at 2 h through to 10 h after coitus. These changes were manifest primarily in cell organelles normally associated with synthesis, in particular the Golgi system and rough endoplasmic reticulum (ER). Two populations of dense-core granules are reported. The small Granules (mean diameter of 950 Å) are probably monoamine in nature; the larger granules (mean diameter 1,450 Å) may contain releasing factors or their carriers. There is no evidence of storage of secreted materials within the perikarya of these neurons. Immediate transport toward the median eminence is suggested.
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.
How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
