Comment TMS vs TDCS (Score 1) 59

Transcranial magnetic stimulation (TMS) works a lot better.
https://en.wikipedia.org/wiki/...

TMS uses a magnetic paddle to induce a current a couple centimeters away from the paddle. This allows for electrical stimulation within the skull that does not cross through the skull.

With direct current stimulation the current passes through your scalp and skull.

Why would you want to pass a current through your scalp and skull? It will cause potentially painful scalp twitching. You'll need to use a higher current because of the resistance of your scalp and skull. This is a cheap gimmick with many downsides compared to TMS.

Comment Why not magnetic? (TMS) (Score 1) 51

It's odd to see transcranial direct current stimulation instead of transcranial magnetic stimulation. Why would you rather have a current pass through your scalp instead of a magnetic field? It feels like the infomercial for the abdominal electrode belt that would give you a six-pack. This is a step backwards towards cheap electrodes that are easily marketed instead of forward toward TMS that can stimulate a wider variety of areas without mildly cooking your scalp.

Comment World's first? (Score 0) 102

I have seen a bounce house before. They're actually pretty common. Bounce houses have some rules about rough play, but can still be used by astronauts. So this is definitely not the world's first inflatable room, for astronauts or otherwise. Perhaps this is "Space's First Inflatable Room"? Or more accurately LEO's first.
