Study says caffeine increases nerve cell activity in the hippocampus
A research team at Hokkaido University in Japan recently confirmed that nerve cells in the hippocampus, which is responsible for memory and learning, form memory by the same mechanism as myocardial cells, and eating caffeinated foods such as coffee can enhance their activity. improve memory.
Caffeine has been known to contract muscles in the past, but the researchers added caffeine to slices of the hippocampus of rats, and the results showed that the concentration of calcium in nerve cells increased within 30 to 60 minutes. the signal transmission of the nervous system has also become very good.
It is reported that the increase in calcium concentration is due to the more active activity of a protein called Renodine II receptor. This protein is also abundant in cardiomyocytes, which can release calcium ions stored in "small cell bodies" in the cells, thus causing the heart muscle to contract. The researchers believe that the enhancement mechanism of this memory formation function in the hippocampus should be the same as that of myocardial contraction.
Because of the high concentration of caffeine used in this experiment, the effect on nerve cells is obvious, but if you want to improve your memory by drinking coffee every day, the concentration may not be enough and will not have any effect. However, the researchers say that if a substance with the same effect as caffeine can be developed in the future, it is believed to play an important role in developing drugs to treat dementia.

In the past, many studies have found that drinking a moderate amount of coffee may have a protective effect on the brain and heart. However, domestic studies have shown that drinking coffee is one of the risk factors of metabolic syndrome, and if the metabolic syndrome is not properly controlled, patients are prone to cardiovascular disease.

After drinking, alcohol is quickly absorbed by the digestive system and then enters the blood circulatory system, affecting the gastrointestinal, heart, liver and kidney, brain and endocrine systems, and leading to disorders of glucose metabolism, protein metabolism and fat metabolism in the body. among them, the most direct and serious victim is the brain. Caffeine, the main ingredient of coffee, can stimulate the central nervous system and muscles, and accelerate aging.
