Hydration signals from the gut travel via the vagus nerve to activate thirst neurons in the SFO. These neurons signal to cells in the median preoptic nucleus, driving animals to drink and the kidneys to conserve water in the bloodstream.
A new Nature study reveals the brain circuits responsible for thirst and satiety.
Researchers have identified a specific network in the brain of mice that drives the need to drink.
A new study reports specialized brain cells in mice predict the hydrating effects of drinking before the liquid can change the composition of the bloodstream.
