A forebrain neural substrate for behavioral thermoregulation

Neuron, 2022
Thermoregulatory behavior is a basic motivated behavior for body temperature homeostasis. Despite its fundamental importance, a forebrain region or defined neural population required for this process has yet to be established. Here, we show that Vgat-expressing neurons in the lateral hypothalamus (LHVgat neurons) are required for diverse ...

Caffeine Effects on Behavioral Thermoregulation

Perceptual and Motor Skills, 1991
Caffeine has a wide range of behaviorally active properties. Varying doses of caffeine solutions were administered (ip) prior to fixed-interval 2-min. schedules of microwave reinforcement in rats tested in a cold environment. Four Sprague-Dawley rats were conditioned to regulate their thermal environment with 5-sec. exposures of microwave reinforcement.

Dynamics of behavioral thermoregulation in the rat

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1991
Past studies have found that the laboratory rat placed in a temperature gradient prefers temperatures that are markedly below its lower critical ambient temperature (LCT), whereas other rodents (e.g., mouse, hamster, and guinea pig) generally select thermal environments associated with minimal metabolic expenditure.

Behavioral thermoregulation by hypoxic rats

Journal of Experimental Zoology, 1992
AbstractTo address whether a shift in hypothalamic thermal setpoint might be a significant factor in induction of hypoxic hypothermia, behavioral thermoregulation was examined in 7 female Sprague‐Dawley rats implanted with radiotelethermometers for deep body temperature (Tb) measurement in a thermocline during normoxia (PO2 = 125 torr) and hypoxia (PO2

Behavioral thermoregulation in the fasted C57BL/6 mouse

Journal of Thermal Biology, 2021
Under relatively cool ambient temperatures and a caloric deficit, mice will undergo daily torpor - a short-term regulated reduction in metabolic rate with a concomitant drop in body temperature. Mice can alternatively achieve metabolic savings by utilizing behavioral changes, such as seeking a warmer environment.

Bombesian alters behavioral thermoregulation in fish

Life Sciences, 1981
Abstract Bombesin was microinjected into the ventricular system of a teleost fish, Catostomus commersoni , in order to evaluate its effects on behavioral thermoregulation in a horizontal thermal gradient. General locomotor activity was also examined.

Effects of Bombesin on Behavioral Thermoregulation in the Bullfrog

Brain, Behavior and Evolution, 2008
Bombesin is a member of a class of neuroactive chemicals that have potent thermoregulatory effects in ectothermic and endothermic vertebrate species. Bombesin-like peptides are found in the brains of ectothermic and endothermic vertebrates and have been implicated in the central nervous system modulation of behavioral thermoregulation.

Behavioral thermoregulation in chicks: The best nest

Developmental Psychobiology, 1997
The ability of prehomeothermic chicks to thermoregulate behaviorally was studied in chicks with continuous access to heated nests, running wheels, and separate sources of high and low protein. In Experiment 1, cold-reared groups with heated or unheated transparent nests ate the same amount and selected the same dietary fractions, but chicks with heated

Behavioral thermoregulation in newborn rabbits.

Journal of Comparative and Physiological Psychology, 1982
Newborn rabbits show behavioral and physiological thermoregulatory responses within the first hours of life. Although the mother prepares a nest for her young, she does not stay with them. The hairless immature young survive by huddling together in the nest. In this study, ambient temperature had a powerful influence on the behavior of newborn rabbits,
