Curr Biol: New results in intestinal and brain axis research! Scientists have revealed the molecular mechanisms by which stomach hunger affects the body's brain memory!

15, 2020 // -- In a recent study published in the international journalCurrent Biology, scientists from the University of Southern California and others found that a hormone that affects how often animals eat also appears to affect the brain's memory.
Animals and humans have a special hormone called ghrelin in their stomachs that tells animals and humans when the body is hungry and helps regulate the body's metabolism, but scientists have been unable to determine exactly how gastric hunger works.
In order to delve deeper into the molecular mechanisms of stomach hunger that affect the body's hunger, metabolism, and memory, the researchers studied the interaction between gastric hunger hormone and the mesmerized nerve, a nerve that sends signals from the intestines to the brain, and then monitored the effects of interference between gastric hunger hormone and the ecstrain nerve on the body's eating and cognitive behavior.
researcher, said: 'We found that rats may not be anxious anymore, but they start eating more frequently.
the absence of gastric hunger signals to the lost nerve not only disrupts the body's blood sugar regulation, but also causes the body to gain weight.

researchers say that increasing the frequency of eating is directly related to memory damage, and that the memory we had the last time we ate affected the time we ate the next time we ate, which made the rats in the study eat faster.
although rats can remember where they got their food, they seem to have forgotten that they have just eaten, so that the rate at which their stomachs are emptied slows down.
researcher Elizabeth Davis said that a particular type of memory in the brains of rats called episodic memory, which helps us remember when we went to school on the first day or what we ate for breakfast yesterday.
Now scientists are trying to gain a deeper understanding of the signaling mechanisms of gastric hunger by studying the ecstasy nerve, as it could help scientists develop more treatments for more metabolic diseases, such as obesity, diabetes or other metabolic diseases, as well as epilepsy and Alzheimer's disease.
researchers say more in-depth research is needed later on to shed light on how gastric hunger signals can be manipulated through the lost nerve, which may be significant for human medical research.
