Functional architecture of behavioural thermoregulation

Area of Science:

• Physiology
• Neuroscience
• Behavioral Science

Background:

• The human thermoregulatory system maintains thermal homeostasis through behavioral adaptation and physiological responses.
• Autonomic and endocrine responses have limitations in extreme environments, highlighting the importance of behavioral thermoregulation.
• The neuroanatomy underlying behavioral thermoregulation was largely unknown until recent research focus.

Purpose of the Study:

• To review current knowledge on behavioral thermoregulation.
• To summarize the state-of-the-art in understanding behavioral thermoregulation.
• To identify future research directions in behavioral thermoregulation.

Main Methods:

• Literature review of recent findings on behavioral thermoregulation.
• Analysis of the distinction between thermal comfort/discomfort and sensation.
• Detailed discussion of thermosensitive neurons and thermoeffector functions.

Main Results:

• Thermal discomfort drives behavior, whereas thermal sensation initiates autonomic thermoregulation.
• Recent research has significantly advanced the understanding of behavioral thermoregulation's neuroanatomy.
• Specific thermosensitive neurons and their roles in thermoeffector functions have been identified.

Conclusions:

• Behavioral thermoregulation is crucial for maintaining thermal homeostasis, especially in extreme conditions.
• Distinguishing between thermal comfort and sensation is key to understanding behavioral drives.
• Further research into the neuroanatomical substrates of behavioral thermoregulation is warranted.
