Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
Thermoregulation01:26

Thermoregulation

The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's forehead...
Quantifying Heat02:46

Quantifying Heat

Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the atoms and...
Body Temperature01:25

Body Temperature

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
Body Temperature01:07

Body Temperature

Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C (97–99°F), remaining relatively stable...

Area of Science:

  • Physiology
  • Thermoregulation
  • Animal Ecology

Background:

  • Hibernation is a seasonal adaptation with poorly understood physiological mechanisms.
  • Interbout arousals, marked by significant body temperature fluctuations, are a key feature of hibernation.
  • Existing models struggle to explain the complex physiological dynamics during hibernation.

Purpose of the Study:

  • To differentiate between hypothesized mechanisms driving interbout arousals in hibernating animals.
  • To develop a model that explains seasonal physiological transitions using body temperature data.
  • To investigate the existence of a universal core regulator for body temperature across species.

Main Methods:

  • Utilized model selection for partially observed systems and dynamical systems theory.
  • Analyzed body temperature data from a free-ranging Arctic ground squirrel.
  • Modified the derived physiological model to incorporate environmental information.

Main Results:

  • Successfully differentiated between two distinct hypotheses for interbout arousals using only body temperature data.
  • Developed a model that captures key features of seasonal physiological transitions.
  • Demonstrated that a modified model qualitatively matches body temperature data across diverse species (bird, shrew, bear).

Conclusions:

  • A low-dimensional, environmentally sensitive core regulator likely controls body temperature across a wide range of species.
  • This finding provides a new perspective on physiological organization and interspecies similarities.
  • The modeling approach is broadly applicable to time-series data from various scientific domains for mechanism elucidation.
