This weird contraption is a Magnetoencephalography (MEG) scanner. It scans … your brain!
Magnetoencephalography (MEG) scanners work by measuring the magnetic field produced by the brain. While MEG scans don’t do a good job of deciphering the geography of the brain, they can easily detect instantaneous changes in brain activity, allowing scientists to track changes that happen in milliseconds.
