Mouse thermoneutral zone

Nettettemperatures, while the thermoneutral zone of the mouse is at 30 1C, so laboratory mice at 20–22 1C are routinely under mild to moderate cold stress, because they are 8–10 1C colder than the equivalent temperature in humans [4,5,11,36,47]. It has been suggested that this persistent cold stress profoundly affects mouse physiology in ways that Nettet27. nov. 2024 · When mice are acclimated to their thermoneutral zone, sympathetic input to the heart is greatly reduced, and a parasympathetic HRV pattern emerges. Both time and all frequency domain HRV parameters increased in both age groups when mice were acclimated to 30 °C, indicative of a large vagal component of mouse heart rate …

Nettet1. jul. 2024 · In 2013, we suggested that, for comparative studies, solitary mice are best housed at 23–25 °C, because this is 3–5 °C below the mouse thermoneutral zone and humans routinely live 3–5 °C below thermoneutrality, and because this generates a ratio of DEE to BMR of 1.6–1.9, mimicking the ratio found in free-living humans.

It was then noted that 21 C lies well below the thermoneutral zone of the mouse, and that their thermoneutral zone is around 30 C. It was therefore postulated that mice should not be housed at 21 C, but
