"It is perhaps not surprising that we might retain at least some functioning neural components [of magnetoreception], especially given the nomadic hunter-gatherer lifestyle of our not-too-distant ancestors," says Kirschvink.
The Caltech study didn’t look at such small changes, however. Magnetic fields inside their test chamber shifted plus or minus 90 degrees at least. As a result, we do not yet know if human magnetorecepton is sensitive enough to detect the more subtle changes typically associated with space weather.
Geomagnetic storms result in very slight changes in the Earth's magnetic field. Not enough to move a compass needle.
I disagree, if the question is whether geomagnetic storms can be "sensed." Because a large and rapid change in magnetic alignment may produce an effect in some people, it does not follow that slight and gradual changes will. Without understanding the mechanism or an experiment which actually tests for it, no such conclusion can be reached.
That the extent of change in orientation included differences as much 90° shouldn't much matter if they can demonstrate the brain reacted during the transition in sufficient sensitivity to the field moving.
It's an interesting experiment. Some people seem to be able to "sense" large rapid shifts in magentic fields. Hopefully there will be follow ups.
The purpose of this experiment was to isolate response to shifts in field 's horizontal alignment and declination/inclination. Which was done successfully.
In Rome the magnetometer recorded a total change of 4.22º over the period of half an hour

no such conclusion can be reached.
Noone asked that question...

It may have an effect on alpha waves, but can people sense those effects? Does it mention anywhere in the study that people can sense these effects? Or are you making claims that are not supported by the article as you so often do?
Can you answer the questions? Or are you just here to call people names?

Is that all you got? Why are you trolling people?
