Artiodactyls and felids have a carotid rete that can cool the blood destined for the brain and consequently the brain itself if the cavernous sinus receives cool blood returning from the nose. This condition is usually fulfilled in resting and modera

The temperatures of the arterial blood and the brain in black Bedouin goats were measured continuously by miniature data loggers. The animals were either euhydrated or dehydrated to 75-80% of the initial body mass by withholding water for 3-4 days du

In species with a carotid rete, the arterial blood destined for the brain can be cooled on its passage through the rete. The temperature difference between the blood before the rete and the brain is termed selective brain cooling (SBC). The onset and

A series of 38 experiments were performed in five conscious goats at air temperatures of +20 degrees C or +30 degrees C to see whether a temperature dependence of spinal cord signal transmission affects the relationships between body temperature and

Adaptive heterothermy and selective brain cooling are regarded as important thermal adaptations of large arid-zone mammals. Adaptive heterothermy, a process which reduces evaporation by storing body heat, ought to be enhanced by ambient heat load and

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°C. The primary effect

The concept prevailing in the first half of the 20th century was that the rostral brain stem contains two interconnected centres, one for heat loss, and the other for heat conservation [29,282]. It was replaced, at the dawn of cybernetics, by the mod

In a hot environment or during intense exercise, mammals must resort to evaporative mechanisms of heat dissipation to maintain thermal balance. As detailed in Chapter 6, the cooling power of evaporation is large, and except in a hot and humid environ

As mentioned before, the thermoneutral zone comprises the central range of envi ronmental conditions in which temperature regulation is achieved entirely by con trol of dry heat loss. The limits of the range are defined by the lower and upper critica
