The latest issue of Nature Neuroscience presents a special issue focused on the state of the art of human brain imaging.
In this issue, BIC Principal Investigator and Director Sylvain Baillet reviews the aspects that uniquely characterize magnetoencephalography (MEG) among the techniques available to explore and resolve brain function and dysfunction. While emphasizing its specific strengths in terms of millisecond source imaging, he also identifies and discusses current practical challenges, in particular in signal extraction and interpretation. He also takes issue with some perceived disadvantages of MEG, including the misconception that the technique is redundant with electroencephalography. Overall, MEG contributes uniquely to our deeper comprehension of both regional and large-scale brain dynamics: from the functions of neural oscillations and the nature of event-related brain activation, to the mechanisms of functional connectivity between regions and the emergence of modes of network communication in brain systems.
"I see MEG and related techniques play an increasing and pivotal role in the elucidation of the grand mechanistic principles of cognitive, systems and clinical neuroscience" claims Sylvain.
Canada's is one of the most productive scientific communities worldwide in MEG electrophysiology and imaging. The BIC operates an MEG program since early 2012. For more information on the program, please visit its website.
