with a MEG, magnetoencephalogram, imager. The researcher measured his
head size and shape with a light pen, and the glasses were like a gps
so data points stayed in calibration when his head moved. The MEG
device was in its own room and looked like a giant white helmet with
an open place to lay your head. Four electrodes measured his magnetic
waves while he listened to rhyming words and tones and touched a
button when they matched. The ear buds kept falling out which the
researchers will improve in future studies.
