ICA Applications in Brain Activation Studies: Algorithm Implementation and fMRI Analysis

ICA achieves dimensionality reduction and isolates independent neural activations in brain imaging studies. This demonstration compares icaMS, icaML, icaMF, icaMF (positive sources), and PCA algorithms using two fMRI datasets: human scans from Hvidovre University Hospital (Denmark) and monkey scans from the EU-funded MAPAWAMO project.
