Figure Lengend Snippet: Multimodal setup in MEG environment. In the pictures, the black cables with fibre optics based sensors attached on the body and head are optical fibres for measurements of cNIBP and NIRS. On the right, shown is performing of simultaneous recording with the setup. During imaging, the display is used to instruct the subject to perform the given task.

Figure Lengend Snippet: Comparison of mean power values (black dots, whiskers = SD) measured with magnetometers ( a ) and planar gradiometers ( b and c ), with (x axis) and without (y axis) the multimodal setup. For better visualisation the plots show an extract of all data, which were shown in each inset separately. In all cases the data can be well explained by a linear fit (red line). Note the slight positive intercept of the linear fits due to smaller power values when the multimodal setup is applied. The external sensors for NIRS are attached on back of the head and on forehead above left eye. Sensors for cNIBP are attached on chest and neck (see Figure ).

Figure Lengend Snippet: Averaged responses for PTT ( a ), BP ( b ), HR ( c ) measured with the cNIBP device; HbO/Hb ( d ) measured with the NIRS device from back of the head and four scouts (MEG) covering visual (green line), auditory (brown line), motor (dark yellow line) and temporal pole (blue line) brain areas ( e ). Average for NIRS and cNIBP data was calculated using values obtained during 4 breath holding sequences. Vertical bars represent standard deviation of the values. In addition, ( f ) shows an averaged response of 8 breath holds using the same breath hold task but recorded independently with our MREG multimodal setup . In all subfigures t = 0 marks the beginning of breath holding for 30 s, highlighted with grey area.

Figure Lengend Snippet: Location of the fNIRS optodes. Red dots are light sources, red dots are detectors, black dots are estimated channels, white dots are 10/20 landmarks. Black lines areas indicate the regions of interest (ROIs): MPPC; medial posterior parietal cortex or Brodmann area (BA) 7, LPPC; lateral posterior parietal cortex BA 7 and 40, MPC; medial parietal cortex BA 2 and 5, LPC; lateral parietal cortex DLPFC; , dorsolateral prefrontal cortex BA 8 and 9; aDLPFC, anterior dorsolateral prefrontal cortex lateral posterior parietal cortex. BA 9 and 46. The axes refer to the MNI (Montreal Neurological Institute) coordinate system. The brain image was generated by a MATLAB-based toolbox .

Article Snippet: The fNIRS data were preprocessed using MATLAB 2018b ( ) and the MATLAB based fNIRS-processing package HomER2 ( ) (for the preprocessed pipeline see https://github.com/SimonSkau/AX_adult_paper_2021.git ).
