Neuromag: Neuromagnetic Recording System

MEGThe Neuromag® is a state-of-the-art neuromagnetic recording system capable of non-invasively recording magnetic fields produced by neuronal activity occurring within the brain. This observed data is called the magnetoencephalogram (MEG) and is analogous to the electroencephalogram (EEG) but represents the magnetic fields produced by ion flow associated with neuronal activity rather than the electric potentials measured in the EEG.

 

This system is designed to:

Magnetic fields are found whenever there is charge flow (current), whether in a wire or neuronal tissue. The orientation of the magnetic field is governed by the right hand rule which essentially constrains the MEG system to sensing magnetic fields produced by groups of neurons located tangentially to the cortical surface.

 

The magnetic field passes unaffected through brain tissues and the skull, so it can be recorded outside the head by the Neuromag system.
