Special Issue Information

Dear Colleagues,

A central paradigm in modern neuroscience is that even simple cognitive processes require anatomical and functional connections working together as a network and that these brain regions are organized in a way such that information processing is near-optimal. Now, algorithms and computational tools aim to identify and assess these networks and also to provide important findings in different EEG applications.

Brain connectivity thus consists in to analyse the spatially distributed but functionally connected regions that process brain information, and this rests upon three different but related forms of connectivity: Anatomical connectivity (AC), Functional connectivity (FC) and, Effective connectivity (EC).

This special thematic issue of Brain Sciences aims to assemble new theoretical approaches and computational solutions in Brain Connectivity Analysis from EEG signal. We invite papers for a special issue: “Brain connectivity analysis from EEG signals: new techniques and computational applications” in Brain Sciences Journal. This special issue welcomes contributions that engage with care in various ways and from a range of EEG applications. We welcome papers that computationally, methodologically and theoretically approach the growing importance of care for Brain Connectivity analysis.

The present work aims to demonstrate the hypothesis that atonal music modifies the topological structure of electroencephalographic (EEG) connectivity networks in relation to tonal music. To this, EEG monopolar records were taken in musicians and non-musicians while listening to tonal, atonal, and pink noise sound excerpts. EEG functional connectivities (FC) among channels assessed by a phase synchronization index previously thresholded using surrogate data test were computed. Sound effects, on the topological structure of graph-based networks assembled with the EEG-FCs at different frequency-bands, were analyzed throughout graph metric and network-based statistic (NBS). Local and global efficiency normalized (vs. random-network) measurements (NLE|NGE) assessing network information exchanges were able to discriminate both music styles irrespective of groups and frequency-bands. During tonal audition, NLE and NGE values in the beta-band network get close to that of a small-world network, while during atonal and even more during noise its structure moved away from small-world. These effects were attributed to the different timbre characteristics (sounds spectral centroid and entropy) and different musical structure. Results from networks topographic maps for strength and NLE of the nodes, and for FC subnets obtained from the NBS, allowed discriminating the musical styles and verifying the different strength, NLE, and FC of musicians compared to non-musicians.

The present study investigates the relationship between individual differences in verbal and non-verbal cognitive abilities and resting-state EEG network characteristics. We used a network neuroscience approach to analyze both large-scale topological characteristics of the whole brain as well as local brain network characteristics. The characteristic path length, modularity, and cluster coefficient for different EEG frequency bands (alpha, high and low; beta1 and beta2, and theta) were calculated to estimate large-scale topological integration and segregation properties of the brain networks. Betweenness centrality, nodal clustering coefficient, and local connectivity strength were calculated as local network characteristics. We showed that global network integration measures in the alpha band were positively correlated with non-verbal intelligence, especially with the more difficult part of the test (Raven’s total scores and E series), and the ability to operate with verbal information (the “Conclusions” verbal subtest). At the same time, individual differences in non-verbal intelligence (Raven’s total score and C series), and vocabulary subtest of the verbal intelligence tests, were negatively correlated with the network segregation measures. Our results show that resting-state EEG functional connectivity can reveal the functional architecture associated with an individual difference in cognitive performance. Full article
