AI Article Synopsis
- Artiodactyls, or even-toed ungulates, use selective brain cooling (SBC) to manage brain temperature during overheating situations.
- In wild antelopes, SBC can occur even at lower body temperatures and does not activate when brain temperatures approach 42 degrees Celsius.
- The main role of SBC is to regulate heat loss mechanisms based on the level of heat stress, rather than to specifically safeguard the brain from heat damage.
Article Abstract
Artiodactyls employ selective brain cooling (SBC) regularly during experimental hyperthermia. In free-ranging antelopes, however, SBC often was present when body temperature was low but absent when brain temperature was near 42 degrees C. The primary effect of SBC is to adjust the activity of the heat loss mechanisms to the magnitude of the heat stress rather than to the protection of the brain from thermal damage.
