NORTHERN IRELAND FUNCTIONAL BRAIN MAPPING (NIFBM) FACILITY
Welcome to NIFBM.
The NIFBM is the only brain imaging system anywhere in Ireland and only one of nine in whole of UK to use the recently developed brain imaging modality, Magnetoencephalography (MEG), to measure brain activity. This is one out of only 170 active MEG labs worldwide.
This facility is a joint investment of £5.3M from Invest Northern Ireland (INI) and Ulster University, and is located at Intelligent Systems Research Centre (ISRC) of Magee campus. It is equipped with the latest whole head 306 channels Elekta Neuromag MEG TRIUX system.
This unique infrastructure is available for clinicians and researchers from inside and outside of Ulster University. Please don't hesitate to contact us if you have any questions or if you are interested in visiting or accessing the NIFBM facilities and support.
MEG provides a direct measure of electrical activity in the brain.
MEG has a very high temporal resolution in the order of milliseconds (ms).
MEG also has an excellent spatial resolution and is capable of localizing sources with an accuracy of millimetres (mm).
It is a non-invasive technique which does not require any contrast injection.
It is comfortable for subjects/patients. Unlike MRI, MEG does not produce any noise during scanning
In clinical applications, MEG is used for pre-surgical evaluation of brain tumour, arteriovenous malformation (AVM) and epileptic focus.
In research, MEG is known to produce better localized responses in the brain as a result of a better signal-to-noise ratio compared to EEG and a more straightforward biophysical formulation. It is widely used to study cognitive processes.
Although less explored but it can be used for the development of Brain-Computer Interfaces, and an analogue to EEG applications. In this case, it can be used essentially to inform EEG about effective biomarkers and learn better about brain dynamics using more active stimulation tasks.
