Was curious about what causes you to gradually lose hearing and sight for a few seconds
Edit: more accurate word would be fainting I think, not native
In: Biology
Need to know more context. Like from getting a head injury?
To cover some basic situations, cutting off blood flow quickly stresses the cells in your brain. Can’t really sustain consciousness if the basic task of being alive is not going so well. It takes a lot of energy to sustain brain activity.
From getting hit in the head it’s because your brain was injured. You try doing work when someone kicks you in the gut haha. The networks get interrupted bc of injury. If it’s real bad, you may have permanent brain damage. Mild is concussion. But don’t be tricked, concussions are bad too. They can really fuck you up. Which makes sense: injuring your brain is bad.
Sleep: it’s part of a normal cycle of activity. Your brain is just going into a different operating mode basically. Normally it’s in “produce consciousness mode.” Sleep is “let’s clean stuff” mode. It has specific patterns of activity it goes through during that time.
Last bit of info: consciousness is still mysterious. But we do know for sure that you need a functioning reticular activation system in the brain. If you damage that, no consciousness ever again. It’s in the brain stem.
