Whole brain functional connectivity: Insights from next generation neural mass modelling incorporating electrical synapses

An overview of data types discussed in this paper.
In all cases, the data presented is an average over 10 subjects’ datasets from the Human Connectome Project database, and is downsampled onto a 68 node network using the Desikan–Killiany atlas. A MEG FC matrices computed via the ‘Multivariate Interaction Measure’ (12) within 8 different bands, which fall into the classical frequency bands α to γ, where β and γ are further divided into 2 and 3 sub-bands respectively. B BOLD FC is computed by z-scoring parcellated BOLD time series data before computing the pairwise Pearson correlation for all node pairs. C Structural data is constructed by applying a probabilistic tractography process to diffusion MRI data. The data is then normalised by row-sum. Visualisations of the structural network are provided for the two hemispheres.
