ASTRONAUTS' BRAIN

I've just listened a recording talking about how astronauts' brain can change with the different space travels, also for gravity's changements that let them fly or drop. This discovery seems very important for doctors that could improve their skills in this content 'cause they could discover how our neurons are connected among them. It could help future scientists for their researches and works to know something more about human brain that's considered like an "unexplored universe".
