Yawning facilitates cooling of the brain, explains Epstein. This happens via blood flow, the inhalation of cool air, and the occasional tearing of the eyes. It has also been found that yawning ...
In a new study, researchers from the University of Nottingham looked at the brain to determine what makes yawning contagious. The BBC reports it happens in the part of the brain that controls ...
Another notion states that yawning is the body's way of controlling brain temperature. [27] [28] In 2007, researchers, including a professor of psychology from the SUNY Albany (US), proposed yawning may be a means to keep the brain cool. Mammalian brains operate best within a narrow temperature range.
Yawning. We all do it and yet there's no set explanation on why we do it. And just as mysterious is that the act of yawning seems to be contagious. A new study looking at that issue has found that ...
Cortical cooling refers to the cooling methods restricted to the cerebral cortex, where most higher brain processes occur. Neuroscientists generate various studies to help explain many of the complex connections and functions of the brain .
By cooling blood directly, cardiopulmonary bypass also cools people faster than surface cooling, even if the heart is not functioning. In 1959, using cardiopulmonary bypass (CPB), Barnes Woodhall and colleagues at Duke Medical Center performed the first brain surgery using DHCA, a tumor resection, at a brain temperature of 11 °C and esophageal ...

Clouding of consciousness, also called brain fog or mental fog, [1] [2] occurs when a person is slightly less wakeful or aware than normal. [3] They are less aware of time and their surroundings, and find it difficult to pay attention. [ 3 ]
