People are embedded in social interaction that shapes their brains throughout lifetime. Instead
of emerging from lower-level cognitive functions, social interaction could be the default …

… These methods employ the (weighted) ℓ 2 -norm of the current distribution as regularizer.
The important practical benefit of such ℓ 2 solvers is that the inverse problem is linear and, …

… A practical benefit of ℓ 2 solutions is that they yield physiologically plausible, temporally …
To avoid smeared ℓ 2 estimates, sparsity-promoting priors such as ℓ 1 -norm prior may be …

To successfully interact with others, people automatically mimic their actions and feelings.
Yet, neurobehavioral studies of interaction are few because of lacking conceptual and …

… Parkkonen and colleagues 110 recently used frequency tagging to follow brain activations
related to the bistable percepts of Rubin's vase-face image. Uniformly distributed dynamic …

… The intrinsic frequency resolution of the non-parametric spectral estimate is limited by the
length L of the moving window, and equals 1/L. The interpretation of the frequency of the peak …

… MEG offers a good spatial and temporal resolution, on a millimeter and millisecond scale,
often making it possible to find the position of sources not revealed by EEG [l, 21. …

… We defined the topography power of ith source as the l 2 -norm of the source topography
squared, ∥ t i ∥ 2 . If we assume that all sensors in the array have equal sensor noise variance …

The spatial resolution of magnetoencephalography (MEG) can be increased from that of
conventional SQUID-based systems by employing on-scalp sensor arrays of eg optically-…

Analysis of spontaneous EEG/MEG needs unsupervised learning methods. While independent
component analysis (ICA) has been successfully applied on spontaneous fMRI, it seems …
