How to get MNI coordinates for Epilepsiae electrodes

One of the best databases for focal epilepsy research is the Epilepsiae database of over 100 annotated datasets of inpatient intracranial and scalp electrode recordings from individuals suffering from epilepsy. It is a fantastic resource. However, it is not clear how to interpret the intracranial electrode coordinates given the current state of the Epilepsiae documentation. … More How to get MNI coordinates for Epilepsiae electrodes

Linear spatial filters (e.g., ICA, PCA) cannot perfectly extract EEG/MEG sources

Linear spatial filters (LSFs) derived from techniques like independent component analysis (ICA) or principal components analysis (PCA) are extremely popular techniques for analyzing electroencephalographic (EEG) and magnetoencephalographic data. They work by exploiting the fact that different EEG/MEG signal sources (e.g., a cortical patch or the eyes) project across the scalp with different topographies. An LSF … More Linear spatial filters (e.g., ICA, PCA) cannot perfectly extract EEG/MEG sources
