The neurobridge project aims to investigate an approach to reconcile structural and functional neural connectivity to design dynamical models of the cerebral cortex. The goal is to use both functional and anatomical data to create a model that can simulate the dynamics of the brain and provide insights into its connectivity.
This project involves using both graph theory and machine learning tools to analyze brain connectivity data and apply dynamic modeling techniques to represent how different regions of the brain interact with each other.
- Import and pre-process biological data on structural and functional connectivity.
- Design a dynamical network model to reproduce biological data features.
- Validate the designed model.
The project will use existing tools and algorithms for connectivity analysis:
- Peixoto's clustering algorithm using the graph-tool library.
- Baruzzi's method for integrating structural data and functional data.
The dataset provided contains two matrices:
- Functional Matrix (
matrices.mat): A correlation matrix between 116 brain regions (116x116) across 30 patients (300 sessions in total). - Connectivity Matrix (
matrices_HNU1.mat): A structural matrix representing the number of nerve bundles connecting the regions.
