CDT Seminar: Measuring the brain’s magnetic fields
I will introduce the field of Magnetoencephalography (MEG) – the measurement of magnetic fields due to neuronal activity. This technique allows us to track human brain function non-invasively and millisecond by millisecond. MEG systems, based on superconducting sensors have been around for some time now. Their clinical application has however been slow to take off. Recently a new generation of optically pumped sensors have become available. These sensors are compact and light enough to be worn within a helmet. I will talk about our latest work moving towards the goal of clinical application of these devices.
Professor Gareth Barnes’ main interest is Magnetoencephalography (MEG), the measurement of magnetic fields created by electrical activity in the human brain.
Most of his research has been the on the development of methods to estimate brain activity based on these measurements and the verification that these methods work through simulation, or comparison with what we know about brain anatomy and function from techniques such as MRI and fMRI and direct invasive recordings from the cortical surface.
The main aim of his work, and the goal of most MEG researchers, is to provide a millisecond by millisecond picture of the electrical activity changes in the human brain.
