Description

Dataset for the publication: 'Structure-function coupling increases during interictal spikes in temporal lobe epilepsy: a graph signal processing study'
Rigoni et al. 2023, Clinical Neurophysiology, doi: https://doi.org/10.1016/j.clinph.2023.05.012

Dataset description

func_data.mat : source-reconstructed EEG traces stored in a Fieldtrip format (data for each subj)

struct_data: consensus structural connectome

ROIpatch : mesh used to plot Fig4

SC_surrogates (W0): 1000 degree-preserving surrogates of the structural connectome computed with the null_model_und_sign function of the Brani Connectivity Toolbox; W0 are used for broadcasting analyses, section 2.6.2

SC_surrogates_harmonics (U0) : network harmonics of the surrogate structural connectomes (W0); U0 are used for broadcasting analyses, section 2.6.2
BD_surr : Broadcasting-direction (BD) of the degree-preserving surrogates of the structural connectome W0; used to produce FigS3 (data for each subj)

PHI : matrix of +1/-1 to generate the functional surrogates used to define significance of SDI, as described in section 2.6.3

data_GSP2_surr : SDI of the functional surrogates used to define significance of SDI, as described in section 2.6.3 (data for each subj)

 

Abbreviations:

EEG= electroencephalography;

SDI= structure-decoupling index
