How do you keep air clean in microgravity, ie somewhere like the ISS? Could you centrifuge it to fling moisture particles to a water trap on the outer edge of the spinner? If you spin it really fast, could odor molecules be removed by this method? I assume toilets work by using a current of air to draw urine etc into a toilet system, how is that air seperated from the waste products, and de-odorized for re-use? If you used particulate filters to clean the air, how would you then clean the filters? Thanks in advance 49.197.186.70 (talk) 07:47, 22 December 2016 (UTC)
Thanks for those good references. OP 49.197.199.21 (talk) 23:51, 23 December 2016 (UTC)
What does it mean "firing" when it's mentioned in a context of measuring electrical activity in nervous system? (This is the exact text: "Measuring neuronal activity, generating action potentials, and recording the firing of individual neurons." another example: "Electrical activity of neurons is being measured. They fire prior to and at the beginning of inhalation") 93.126.88.30 (talk) 16:09, 22 December 2016 (UTC)
"Electrical activity of neurons is being measured. They fire prior to and at the beginning of inhalation. Where are these neurons situated?" The answer is Medulla oblongata. Now my question is why do they fire prior to the inhalation? (I understand why they fire at the beginning but I don't understand why they fire prior to it)93.126.88.30 (talk) 16:44, 22 December 2016 (UTC)
Thank you! that absolutely sounds logical. 93.126.88.30 (talk) 17:39, 22 December 2016 (UTC)
