Scientists magazine reported that researchers found in mice who played a thirst “switch” role of two different genes of neurons. Scientists have used optical gene technology to design experiments that use neurons to express neurons in light sensitivity. They speculate that some neurons are involved in the thirst or satisfaction of mice.
When the research team used the laser to stimulate the thirsty neurons of the rats, even though they had drunk enough water, they would be very greedy to drink water. On the contrary, when the research team used laser to stimulate another group of people responsible for “turning off” thirsty neurons, even if they are actually very thirsty, but did not drink a little water. At present, the researchers are not clear, the mouse thirsty dual mechanism is applicable to other mammals.
