Eli5 – what happens to our brain at zero gravity? Do cells float like our bodies do? Are thought processes manipulated?
In: 10
Your brain is already like jelly. There’s some connective tissue and cerebrospinal fluid in your head along with it to help protect it from movements in your daily life. In Zero Gravity, the brain still sits comfortable in that fluid and doesn’t bounce around the walls of the skull any more than it would in daily life, for the most part.
Thoughts will not be affected because thoughts are just electrical signals between the cells, just like nerves in the body. The cells remain intact and connected while in Zero Gravity, so no harm comes to thoughts.
There is a possibility of some initial headaches and discomfort due to blood being redistributed more evenly in Zero-G, but astronauts claim to become accustomed to the sensation.

Good answer above.
Your body has a 3D collagen structure that holds cells in place. So cells stay where they’re supposed to.
Only regions with room/space can have free floating material: like in the intestines and airway.
