Figure 1: Distribution of stimulation points in M1 (panel A) and mPFC (panel B), in the two experimental sessions (PE: blue dots; AE: red dots), represented in the MNI space by using a template cortical surface. Green dots represent the four electrodes surrounding the stimulated area, which were used for the efficiency analysis (see text and figure 6 for details).

EEG-assisted retrospective motion correction for fMRI (E-REMCOR) and automated implementation (aE-REMCOR)

by Jerzy Bodurka1,2,3 1Laureate Institute for Brain Research, Tulsa, OK, USA 2Stephenson School of Biomedical of Engineering, 3Center for Biomedical Engineering, The University of Oklahoma, Norman, OK, USA Synopsis Electroencephalography (EEG) concurrently acquired with fMRI provides high temporal resolution information about brain activity as well as subject head movement. We introduced an EEG-assisted retrospective motion…

Independent Component Analysis – demystified!

by Dr. Markus Plank Scientific Consultant (Brain Products) For some researchers, Independent Component Analysis (ICA) to a certain extent might still be equivalent with a black box, which magically alters the data and produces “cleaner” signals. In this article, I would like to take you by the hand and demystify the theoretical background, requirements and algorithms…
