    Evidence for a Human Geomagnetic Sense

    Research shows the changes in alpha wave amplitude — a measure of whether the brain is being engaged or is in a resting or “autopilot” mode — following rotations of an Earth-strength magnetic field. On the left, counterclockwise rotations induce a widespread drop in alpha wave amplitude. No drop is observed after clockwise rotation or in the FIXED condition.

    Scientists develop a robust experiment that shows human brain waves respond to changes in Earth-strength magnetic fields. Many humans are able to unconsciously detect changes in Earth-strength magnetic fields, according to scientists at Caltech and the University of Tokyo.

    The study, led by geoscientist Joseph Kirschvink (BS, MS ’75) and neuroscientist Shin Shimojo at Caltech as well as neuroenginee...
