When Napoleon realized "Army marched on its stomach," he may have done something. According to new research, hunger is more powerful than thirst, anxiety, fear, social needs.
The team headed by researchers at the National Institutes of Health found that starvation is the most important driving force for mice. Indeed, the team discovered that the advantage of starvation surpasses other instincts. As a result, mice risk compromising more time to endanger their lives. In addition, the team found that guinea pig related peptide (AgRP) neurons play an important role in starvation as the most important driving force and outlined the behavior of these neurons.
For their research, the team conducted a series of experiments. For example I took food and water from a 24-hour rat and then looked at which resource I got when I chose. How to react Hunger is not only proven to be more powerful thrust than safety and thirst, it is more important than socializing. For example, in one experiment, socially isolated mice can choose to spend in a room that has food or a room with other mice. Those satisfied mice chose a companion of another mouse strongly, but hungry mice chose a room containing food.
Michael Krashes, a researcher at the project, said in a recent statement: "We are continuing to exist and pursuing a series of actions in the presence of other species, all of which are dominated by our nervous system It has been". "Of course, we can not pursue all these motives right away so we need to choose the most important motive at different times of demand." In the course of evolution, we are constantly "correct" in place of other animals, The animals who chose the motive survived. Next is the power of food-led food.

Why am I hungry? Mechanisms that control hungry signals can lead to obesity drugs.
The relationship between hunger and meal, and thirst and alcohol intake is usually weak. This is due in part to the limits of these sensory measurements, which are typically dependent on descriptive time indicators, motivation, metabolism, and / or self-declaration. Each has undergone a rigorous review. Equally problematic is the decisive consumption of intake behavior - the supplementary concept can not explain multiple violations of cognitive, social, sensory and logistic factors. Hunger and thirst have similar purposes, but there are also big differences in health effects. Of particular note is that a higher and more stable observation of thirst may be more exciting than starvation rather than hunger and thirst. Combining these observations with the evidence that the satiety value of the beverage is limited presents unique challenges and opportunities. Conclusion: 20060847
If you are concerned about news about nutrition, you may have read that you heard, and that people do not drink frequently thirsty, but misunderstand hunger. Just sent to dozens of articles containing this paragraph to use online "mistake thirst starvation" word search: As a society, we are used to surprising us in contact with our experience contradiction Scientific discovery It is easy to accept the view that humans do not know the difference between their most sensational two most fundamental and important views. But let's think about it: Do hunger (wobble etc.) resemble thirst (throat etc.)? It is possible to develop the evolutionary process of these ideas so that all animals possessing them, including wild prairie dogs as well as humans, are completely confused as to when to eat and when to drink Is it?
