MEG

Magnetoencephalography or MEG is a non-invasive neuroprosthetic technique which functions by measuring changes in the tiny electromagnetic field that surrounds the brain.

The problem that arises is that the electromagnetic field is weak compared to normal background noise. So, special highly sensitive detectors called superconducting quantum interference devices or SQUDS are used to minimise this ratio. Even so, they can only detect the field itself. Special algorithms are utilised to try and determine the rough location in the brain.
