What happens to our brains when we drink scraps?

Every bosom friend has several glasses of wine. From ancient times to the present, from literati to ordinary people, there may be times to have a good drink. According to relevant statistics, among the 65.438+38.6 million people in China, the average person consumes about 23 kilograms of wine every year. Make an appointment with three or five friends, meet at the wine table, drink until you are unconscious, and wake up the next day with a blank head. What happens to our brains when we drink scraps?

Alcohol is actually a fat-soluble substance, which can freely penetrate the blood-brain barrier and cause certain damage to the central nervous system of the body. To understand why drinking is fragmented, we can think of the brain as a video recorder. When the human brain works normally, it can record what it sees and hears like a video recorder, and it can also be played back when it is recalled afterwards. The temporal lobe of the brain is actually the area responsible for storing memories, that is, the memory card of the video recorder.

Once you drink too much, alcohol will affect the activation of nerve ion channels, indirectly affect the function of pyramidal cells in hippocampal CA 1 area, and then affect your memory function. In our brain, there is a prefrontal cortex tissue, which is mainly used to store short-term memories. Another tissue in our brain, the hippocampus, is responsible for weaving short-term memories and storing them for a long time.

But after storing these memories, a special neurotransmitter (NMDA-GABA) is needed, and alcohol will directly hinder the work of neurotransmitters. If we drink too much, the neurotransmitters in the brain will be disordered, alcohol will start to paralyze the temporal lobe of the body, and the activity of the hippocampus will be inhibited to a certain extent, so that it is impossible to record information completely and fragmentation will occur.
