Protection of the brain against heat damage

Journal of Physical Fitness and Sports Medicine, 2014
In homeothermic animals, metabolic heat production in the brain is higher than in other tissues. However, cerebral tissue is susceptible to heat. Several animals have mechanisms that selectively cool the brain during hyperthermia (i.e., selective brain ...

The Genetic Architecture of Early Body Temperature and Its Correlation With Salmonella Pullorum Resistance in Three Chicken Breeds

Frontiers in Genetics, 2020
New-born chicks are vulnerable to bacterial infections and not good at regulating body temperature. There is a close relationship between thermal regulation and immunity, however, the underlying mechanism is not well understood.

Assessment of brain mechanisms involved in the processes of thermal sensation, pleasantness/unpleasantness, and evaluation

IBRO Reports, 2019
The conscious perception of thermal stimuli is divided into two categories: thermal sensation (i.e., discriminative component) and pleasantness/unpleasantness (i.e., hedonic component).

The Torpid State: Recent Advances in Metabolic Adaptations and Protective Mechanisms†

Frontiers in Physiology, 2021
Torpor and hibernation are powerful strategies enabling animals to survive periods of low resource availability. The state of torpor results from an active and drastic reduction of an individual’s metabolic rate (MR) associated with a relatively ...

Estrogenic modulation of female thermoregulatory behavior in a cold environment

Journal of Physical Fitness and Sports Medicine, 2016
Thermoregulation is categorized as either autonomic (i.e., sweating, shivering) or behavioral (i.e., wearing clothes, usage of air conditioner) thermoregulation. Compared to autonomic thermoregulation, the neural pathway of behavioral thermoregulation in

Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]

, 2015
The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.
