Scientists at EPFL[*] in Switzerland have shown that you are more likely to initiate a voluntary decision as you exhale. Published in today's issue of Nature Communications, these findings propose a new angle on an almost 60-year-old neuroscientific debate about free will and the involvement of the human brain.
"We show that voluntary action is indeed linked to your body's inner state, especially with breathing and expiration but not with some other bodily signals, such as the heartbeat," explains Olaf Blanke, EPFL's Foundation Bertarelli Chair in Cognitive Neuroprosthetics and senior author.
At the center of these results is the readiness potential (RP), a signal of brain activity observed in the human cortex that appears not only before voluntary muscle movement, but also before one becomes aware of the intention to move. The RP is the signature of voluntary action since it consistently appears in brain activity measurements right before acts of free will (like being aware that one wants to reach for the chocolate).
[...] These findings suggest that the breathing pattern may be used to predict 'when' people begin voluntary action. Your breathing patterns could also be used to predict consumer behavior, like when you click on that button. Medical devices that use brain-computer interfaces could be tuned and improved according to breathing. The breathing-action coupling could be used in research and diagnostic tools for patients with deficits in voluntary action control, like obsessive compulsive disorders, Parkinson disease, and Tourette syndromes. Blanke and Hyeong-Dong Park, first author of this research, have filed a patent based on these findings.
[...] More generally, the EPFL findings suggest that acts of free will are affected by signals from other systems of the body. Succumbing to that urge to eat chocolate may depend more on your body's internal signals than you may realize!
Blanke elaborates, "That voluntary action, an internally or self-generated action, is coupled with an interoceptive signal, breathing, may be just one example of how acts of free will are hostage to a host of inner body states and the brain's processing of these internal signals. Interestingly, such signals have also been shown to be of relevance for self-consciousness."

Indeed most of the time when something about "free will" in brain research is presented (at least to a general audience, I have no idea what happens inside the brain science community), there's some (implicit or explicit) distinction done between "you" (who are "proven" to have no free will) and "your brain" (which actually controls you, "disproving" the free will). But that does make no sense to me. My brain is not something separately from me. If I do something, then my brain does it, and if my brain does something, then I do it. So if my brain controls my behaviour, then that's self control, and actually what would be expected of free will!
Now if they detected that my decisions are preceded by some signal from outer space, that is when I would start to worry about not having free will.

Agree.
Phew!

But were you inhaling, exhaling, or holding your breath at the point you agreed? ;)

the universe would be broken otherwise, that is if motor action happened at the same time or earlier.

If that happened for everybody else too, it merely shifts the problem of verification of free will from your brain to the source of the signal.
Basically, the brain being analog, already puts it in the domain of quantum scale resolution for triggering neurons. So, there is the as yet impossible to model "signal from beyond space" that affects the brain. Also there is the problem of optimization, apparently damaged or small brains perform too well for the model of 'the brain is the cpu'. Either nature doesn't optimize (by shrinking the brain or by letting the more endowed ones use it fully) or we are missing some different ways for the brain to work.

How can you be sure? Maybe it is so your brain wants you to think?

I dunno if I dunno or if the brain wants that I dunno by withholding information.
