Classification-based approaches for data analysis are provoking wide interest and increasing adoption within the neuroscience community. Topics like "brain decoding", "multi-voxel pattern analysis" and "brain-computer interface" are prominent examples of this trend. The core problem of these investigations is hypothesis testing, i.e., finding evidence of some effect produced...
Electrical cortical stimulation (CS) of the auditory cortices has been shown to reduce the severity of debilitating tinnitus in some patients. In this study, we performed MEG source imaging of spontaneous brain activity during concurrent CS of the left secondary auditory cortex of a volunteer suffering from right unilateral tinnitus. CS produced MEG artifacts which were successfully sorted and removed...
The functional connectivity of the brain has been studied here using knowledge from two different scientific fields. The methods of Synchronization Likelihood and network theory are applied to magnetoencephalography (MEG) data in an effort to analyze the brain as a complex network. These studies show an interesting small-world phenomenon in functional connectivity. Network and head-map images of the...
Recent technological advances have led to a large increase in the volume and quality of recordings from the brain. For example, while traditional electrophysiological recordings relied on painstaking observations of single neurons, it is now increasingly possible to record from tens or even a hundred neurons simultaneously. Similarly, electro and magnetoencephalographic recordings are routinely performed...
