An ANR international collaboration project

Abstract

An ANR international collaboration project was obtained in 2020.
This project focuses on the estimation of brain connectivity graphs with an innovative spatio-temporal approach his project is in  collaboration with the University of Santa Barbara in the USA and the University of Lausanne in Switzerland

Coordinators of the project

  • Alex Petersen (Brigham Young University)
  • Wendy Meiring (University California Santa Barbara)
  • Jonas Richiardi (Lausanne University)
  • Emmanuel Barbier (Grenoble Institut des Neurosciences)
  • Florence Forbes
  • Gullaume Becq and Sophie Achard (Univ. Grenoble Alpes)

Description

This project is at the interface of statistics, network science, and computational neuroscience.
The central objective is to develop methods for robust and statistically consistent estimation of networks using functional data analysis for multivariate data sets such as observed in neuroimaging. The functioning of the brain is frequently assessed via noninvasive techniques such as EEG, MEG or fMRI, which provide spatio-temporal data. Brain regions are defined based on their specific location of the cerebral cortex where time series are recorded. There is a need to extract accurate spatial and temporal properties of the time series in order to propose robust estimation and construction of brain networks.

Duration of the project

3 years
