Abstract

fetched live from OpenAlex

The forebrain contains neuronal circuits of critical importance in the regulation of food intake. Nesfatin has been identified as a satiety peptide within central neurons. ICV injection of nesfatin‐1 decreases food intake in a dose‐dependent manner and result in a decrease in body weight. However, the central pathways activated by nesfatin‐1 are not known. In this study, the distribution of neurons expressing fos‐like immunoreactivity following ICV infusions of nesfatin‐1 (5 pmol/µl; 2 µl followed by two 1 µl injections every 30 min) was identified in the rat forebrain. Fos labeled neurons were found within the hypothalamus: paraventricular, supraoptic, arcuate, lateral, dorsomedial and posterior nuclei. In addition, the organum vasculosum of the lamina terminalis, median preoptic nucleus and subfornical organ expressed fos labeling. Finally, fos labeling was observed within the midline thalamic nuclei, lateral septum, islands of Calleja, medial preoptic nucleus and medial and central nuclei of amygdala. These data suggest that nesfatin‐1 exerts its anorexigenic effects through the activation of forebrain structures previously implicated in the regulation of food intake and energy expenditure.

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.
