With Electroencephalogram (EEG) it is possible to keep track of temporal changes in the nervous system during a meditation session. Findings in this area can give information about the neuronal responses of meditation, but also in general about the brain in all naturalistic conditions. This study uses a variant of Independent Component Analysis (ICA) called Fourier-ICA to analyze EEG data from meditation sessions and shows that ICA can be used to do much more than just remove artifacts, which is the normal use case in EEG studies. In particular, the answer is sought for the question of whether it is possible by these means to differentiate between neural correlates of focused and wandering mind.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Erkka Heinil\u00e4 (erpipehe) on 2017-05-06 15:43:27.359314.
