David Cohen is a Canadian physicist who measured the first magnetoencephalogram.
After the first measurement of the magnetic field induced by heart’s electric activity, Cohen measured the much weaker field of the human brain; this was the first magnetoencephalogram (MEG). After SQUID detectors were invented, MEGs became as clear as electroencephalograms. Today, MEGs are used in combination with magnetic resonance images for medical diagnostics.
Also, MEGs are used in brain-machine interfaces for the manipulation of robotic prostheses in a non-invasive manner. ByAxon hopes for building a highly sensitive magnetic detector for the bypassing of the injured spinal cord, based on the recordings of the magnetic activity triggered by the neurons.
