Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers. Arrays of SQUIDs(Superconducting quantum interference devices) are currently the most common magnetometer, while the SERF(pin exchange relaxation- free) magnetometer is being investigated for future machines.
The purpose of the human foot is to support and control the direction of the weight as it falls forwards during the stance phase of locomotion and of great importance to the forefoot width and the stabilizing role of the foot is the position and function to the big toe
