Studying the human brain anatomical network via diffusion-weighted MRI and Graph Theory
Our goal is to study the human brain anatomical network. For this, the anatomical connection
probabilities (ACP) between 90 cortical and subcortical brain gray matter areas are …

Realistically coupled neural mass models can generate EEG rhythms
RC Sotero, NJ Trujillo-Barreto… - Neural …, 2007 - ieeexplore.ieee.org
We study the generation of EEG rhythms by means of realistically coupled neural mass
models. Previous neural mass models were used to model cortical voxels and the thalamus. …

Measuring transient phase-amplitude coupling using local mutual information
Here we demonstrate the suitability of a local mutual information measure for estimating the
temporal dynamics of cross-frequency coupling (CFC) in brain electrophysiological signals. …
