[FRIAM] Human Magnetoreception!

[Steven A Smith]

Glen -

As usual, your provocation lead me to speculate and google and speculate
some more.  

 1. Is sleeping E/W significantly different and N/S geomagnetically?  
    (I prefer to be woken by the rising sun, myself, not so clear on the
    geomagnetic implications though)
 2. Does the off-vertical angle of the earth's field (at mid-latitudes
    -N/+S) effect humans, esp. when traveling/moving between
    mid/extreme/equatorial latitudes?  (Might yield something akin to a
    latitudinal version of jet-lag?)
 3. Does wearing a tinfoil hat *in* an electromagnetic field introduce
    fields larger than the geomagnetic field?
 4. Does 3) above qualify for (accidental?) self-medication for mental
    disorders? https://clinicaltrials.gov/ct2/show/NCT03556735
 5. does Randall Munroe (XKCD) read my mind? https://xkcd.com/2098/

>> After a downwards magnetic field rotated counterclockwise, some people responded with a large drop in amplitude of their EEG alpha waves, up to a 60% decrease from pre-stimulus levels. Alpha waves are EEG oscillations that go up and down at a frequency around 10 Hz (10 times per second). They dominate the EEG signal when we are awake with our eyes closed, and arise from the spontaneous, synchronized activity of millions of neurons. Their function is not well-understood, but they may reflect a relaxed mind with nothing in particular to focus on and no particular task to do. When a stimulus suddenly appears and is processed, neurons fall out of synchrony with each other, the alpha rhythm is disrupted, and alpha waves get smaller as a result.
