How does alcohol affect brain cells? Detailed answer
Directory / Big encyclopedia. Questions for quiz and self-education Did you know? How does alcohol affect brain cells? Good news. Alcohol does not "kill" brain cells. It only prevents new cells from growing rapidly. The idea that alcohol supposedly destroys our brain was born in the early XNUMXth century thanks to sobriety advocates who demanded a ban on all alcoholic drinks without exception. No scientific evidence has supported this theory. Samples taken from drinkers and teetotalers showed no significant difference, both in terms of the total number of neurons and in terms of their density. Plenty of other research suggests that drinking in moderation can increase cognition. For example, an experiment conducted in Sweden showed that mice given alcohol grew more brain cells than mice deprived of this pleasure. Alcohol abuse does lead to serious consequences, including for the brain, but there is no evidence that all these problems are somehow related to the death of brain cells - most likely, alcohol simply interferes with the working brain processes. Hangovers are caused by shrinkage of the brain due to dehydration, when our brain is forced to shrink its own protective sheath. It's the shell that hurts. The brain itself does not feel anything - even if you stick a knife into it. The longitudinal groove between the upper lip and the nose, whose name no one ever knows, is actually called a filter. It is thanks to the filter that we can drink beer directly from the bottle, letting air inside. If you had to open a can of beer in zero gravity, all the liquid would immediately pour out and float around you in the form of small spherical droplets. Not so long ago, astronomers discovered a huge supply of alcohol in our region of the Milky Way. This giant cloud of methanol is 463 billion km across. And although the alcohol that you and I like so much is grain alcohol (also known as ethyl alcohol, or ethanol), and methanol is a complete poison, the discovery of scientists in some way reinforces the well-known theory that the Universe was created in order to we drank it.

Where did bananas originate? Bananas are the oldest fruits known in history. The most ancient people knew bananas and admired them. It is believed that bananas originally grew in South Asia, and over the centuries spread to the west and east. The Muslims called the banana palm the tree of paradise, while the Hindus deified bananas. At the beginning of the XNUMXth century, the priest Thomas de Berlanga brought banana roots to the New World. He hoped to win friendship with the Indians with this sweet, golden fruit and thus convert them to his faith. From these little roots grew a whole banana plantation of thousands of acres, which still exists in the tropical region of America! The Indians found a variety of uses for bananas. They fry them while the bananas are green, eat them instead of bread. They boil them like vegetables, stew them, dry them like berries, and even make a strong alcoholic drink out of them! Although we say that bananas grow on a tree, it is actually not a tree, but a bush. It is probably the largest shrub in existence without a tree trunk. The stem, which reaches 3,5 to 9 meters and looks like a real tree trunk, is actually a mass of tough leaves. The most developed banana varieties have lost the ability to produce seeds, which is much more convenient for eating. At the top of the plant is a huge tuft of hanging leaves, bright green in color. It is they that resemble a palm tree, make a banana look like a palm tree. One large flower bud grows in the middle of the trunk. And at the right time, it is on it that fruits appear. Since bananas grow in heavy bunches, the stem of the bush bends down. It turns out that bananas grow upside down. Each bush grows one bunch of bananas, but its weight often reaches 45 kilograms or more! Bananas are always harvested while they are green, even when they are not going to be sent somewhere far away for sale. The reason is that if they are allowed to ripen on the tree, they burst and spoil before they are plucked. Bananas are transported on special ships built to transport bananas. They must be ventilated with a stream of cold air so that the fruits do not ripen during transport.
