Continuous Target Decoding with SPoC

Source Power Comodulation (SPoC) [1] allows to identify the composition of orthogonal spatial filters that maximally correlate with a continuous target.

SPoC can be seen as an extension of the CSP for continuous variables.

Here, SPoC is applied to decode the (continuous) fluctuation of an electromyogram from MEG beta activity using data from Cortico-Muscular Coherence example of FieldTrip
