Scans reveal how brain adapts to life in space

[FfFfFfFF 58,382]

Brain scans of cosmonauts have revealed the first clear evidence of how the organ adapts to the  challenge of moving around in space.

Analysis of scans taken from 11 cosmonauts, who spent about six months each in orbit, found increases in white and grey matter in three brain regions that are intimately involved in physical movement.

The changes reflect the “neuroplasticity” of the brain whereby neural tissue, in this case the cells that govern movement or motor activity, reconfigures itself to cope with the fresh demands of life in orbit.

Images of the cosmonauts’ brains, taken before and after missions lasting on average 171 days, and again seven months later, confirmed that the cerebrospinal fluid that bathes the brain redistributes itself in orbit, pushing the brain up towards the top of the skull. 

“What we see makes so much sense. It’s a sign of the complex situation cosmonauts find themselves in, and that they are learning how to adapt to this very extreme environment,” said author on the study.

Interesting. Personally could never go in space, I think id choose to die on Earth if anything happened here than go to space to survive

I just thought that living in space, or at least zero gravity, could be good for people in wheelchairs or who suffer other body impairments as they would technically have an easier time moving around, compared to the struggle against earth's gravity 

that might not be true for every disabled person, but like some living in a wheelchair, or someone who's paralyzed lower body half, they could have more physical freedom

I haven't thought of it like this before but yeah, it totally makes sense.

That's in movies anyway. If something happened to earth where let's say our ecosystem collapsed or something it would still be easier to survive on earth

 

There's nothing we can build in space we can't build down here including air tight structures and if anything making them bigger on earth would be easier. Plus u have gravity down here and would be easier to build greenhouses and still grab resources

 

The whole if earth gets screwed survive in a space station never made sense to me

True. That's a good point. However on the flip side there's other health effects that come with long term exposure to not gravity so that freedom would come with a cost and side effects
