Getting blackout drunk usually means forgetting what you had done for long periods of time. And while sometimes you’re reminded by friends or family, the real blackout caused by alcohol causes a black spot in your memory.
Total blackouts, also called fragmentary blackouts, actually make your brain stop recording everything, even though you’re able to send drunken text messages or lead a “sophisticated” conversation. The alcohol you have consumed interferes with your hippocampus – the part of your brain, which is responsible for memory formation. When the alcohol interferes with the neurons in your hippocampus, it prevents those neurons from “communicating” with each other and preventing your brain from performing its natural function. In other words, it makes your brain unable to create new memories and record the latest events.
One of the ways to avoid a total blackout is to eat something before you go drinking, since the lack of food in your stomach will raise your alcohol blood level easily.
