Thirst Neurons Anticipate The Homeostatic Consequences Of Eating And Drinking
"Thirst motivates animals to drink in order to maintain fluid balance. Thirst has conventionally been viewed as a homeostatic response to changes in blood volume or tonicity. However, most drinking behaviour is regulated too rapidly to be controlled by blood composition directly, and instead seems to anticipate homeostatic imbalances before they arise. How this is achieved remains unknown. Here we reveal an unexpected role for the subfornical organ (SFO) in the anticipatory regulation of thirst in mice."
The Water In You
"Think of what you need to survive, really just survive. Food? Water? Air? Facebook? Naturally, I'm going to concentrate on water here. Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human adult body is water."
Brain's Thirst Circuit 'Monitors The Mouth'
"cientists have glimpsed activity deep in the mouse brain which can explain why we get thirsty when we eat, and why cold water is more thirst-quenching.
A specific "thirst circuit" was rapidly activated by food and quietened by cooling down the animals' mouths.
The same brain cells were already known to stimulate drinking, for example when dehydration concentrates the blood.
But the new findings describe a much faster response, which predicts the body's future demand for water."
