@TheNeuroBiologist I love how you promote religion and defy science when you call yourself "TheNeuroBiologist"

Therefore, this "static" event is a marker that radio frequencies smurb can clog rancidly toward omnipresence, and glive a queerer view into the world of quantum crahka:)

@madeleinemahin I don't know if you'll ever read this but THANK YOU. This paper was exactly what I was looking for for my presentation on fMRI

@leotakesleo I got this info in my special topics in neuropsychology class, you should read articles written by Logothetis on fMRI, one is called "what you can and cannot do with fMRI" in Nature (I think you need a vpn client or access to get hold of that article). This logothetis guy is an expert on fMRI so it is a good source. Good luck :)

actually it is much more complicated than that. The fMRI is a "capsule" with a magnetic field (usually 1.5 tesla to 3 tesla today), and when inside this magnetic field this will warp the deoxygenatedhemoglobin (which is in our blood in addition to oxygenatedhemoglobin) in our body. The point is that deoxyHb acts like a weak magnet, and with more deoxyHb, less MRI signal and vice versa. It's basically an indirect measurement of neruonal activity. Too much to write for the comment space to allow..
