Area of Science:

Neuroscience
Biomedical Engineering
Data Science

Background:

Independent Component Analysis (ICA) is a multivariate statistical method gaining traction in brain imaging analysis.
Unlike the General Linear Model (GLM), ICA does not require pre-defined spatial or temporal priors for brain responses.
ICA offers a data-driven approach to explore underlying factors in complex datasets like fMRI and EEG.

Purpose of the Study:

To introduce and review the application of ICA for processing functional Magnetic Resonance Imaging (fMRI) and Electroencephalography (EEG) data.
To explore extensions of ICA for population-level analysis applicable to both fMRI and EEG.
To facilitate multimodal integration of EEG and fMRI data through ICA-based decomposition.

Main Methods:

Application of Independent Component Analysis (ICA) for hemodynamic (fMRI) and electrophysiological (EEG) data processing.
Review of existing literature employing ICA for EEG and fMRI data decomposition.
Proposal of an optimized method for symmetric EEG-fMRI decomposition.

Main Results:

ICA provides a flexible alternative to GLM for brain imaging data analysis.
The study reviews various ICA applications in EEG and fMRI, highlighting their utility in multimodal integration.
An optimized method for symmetric EEG-fMRI decomposition is presented.

Conclusions:

ICA is a powerful tool for exploring brain imaging data, reducing the need for explicit response parameterization.
Multimodal integration of EEG and fMRI using ICA offers enhanced insights into brain function.
Further research is needed to address outstanding challenges in multimodal data integration using ICA.
