My postgraduate work with Dr. Emma Chiaraviglio at the Ferreyra Institute concerned the neural control of thirst and salt appetite. This work provided electrophysiological evidence that the brain has osmo-sodium sensors outside the hypothalamus in cells of the Organum Vasculosum of the Lamina Terminalis telencephalon. This nucleus is one of the specialized neural structures called circumventricular organs and it initiates the appropriate behavioral responses to losses of body water and sodium.

Seasonal variation in its body composition and gut length, in relation to reproductive status, was studied. Physical Condition Index PCI and body composition showed seasonal differences, however, there were no differences in intestine length. The PCI was higher for both mature males and reproductive females compared to immature males and non-reproductive females. Lipid, protein and ash content showed differences in relation to reproductive status.
The results suggest that A. This is a preview of subscription content, log in to check access. Rent this article via DeepDyve. Antinuchi C. Google Scholar. Reproductive energetics and thermoregulatory status of nestlings in pampa mice Akodon azarae Rodentia: Sigmodontinae.
