What Happens When Your Brain Can’t Tell Which Way is Up?

In space, there is no “up” or “down.” That can mess with the human brain and affect the way people move and think in space. An investigation on the International Space Station seeks to understand how the brain changes in space and ways to deal with those changes.

Previous research and first-hand reports suggest that humans have a harder time controlling physical movement and completing mental tasks in microgravity. Astronauts have experienced problems with balance and perceptual illusions – feeling as if, for example, they are switching back and forth between right-side-up and upside down.

The Spaceflight Effects on Neurocognitive Performance: Extent, Longevity, and Neural Bases (NeuroMapping) study is examining changes in both brain structure and function and determining how long it takes to recover after returning from space.

Researchers are using both behavioral assessments and brain imaging. Astronauts complete timed obstacle courses and tests of their spatial memory, or the ability to mentally picture and manipulate a three-dimensional shape, before and after spaceflight. The spatial memory test also is performed aboard the station, along with sensory motor adaptation tests and computerized exercises requiring them to move and think simultaneously. Astronauts are tested shortly after arriving aboard the station, mid-way through and near the end of a six-month flight.

Structural and functional magnetic resonance imaging (MRI) scans of the brain are done pre-flight and post-flight.

I'll bet you don't see this on the news.

Well, FUCK. Here's to hoping that this absolutely doesn't happen, and hopefully there's an ability for us to make significant noise about it and be meaningful in doing so.

Also, here's a link to the wikileaks page with a bunch of other analyses on the shitty TPP: https://wikileaks.org/tpp-ip3/

"There is no doubt that this senseless violence is breathtaking," Carson wrote, "but I never saw a body with bullet holes that was more devastating than taking the right to arm ourselves away."

And that is it in a nutshell. He is a sociopath. It's not that uncommon in surgeons, especially in neurosurgery. The field draws them in. Its the perfect fit for a narcissistic person who has no empathy and believes themselves above other people.

Ask yourself if someone who has such callous disregard for human life is the person you want in charge of the US Armed Forces and our nuclear arsenal. I know the idea terrifies me.

From that other social site

The weather didn't cooperate.  One quick shot at the beginning of the eclipse through heavy clouds; later, the moon rose above the clouds, but the color was gone.

Happy 100th birthday, Syd! Great to meet a fellow aviator at the Canada Aviation and Space Museum​.
