Multivariate analysis of functional MRI data of psychiatric patients by using soft-computing approaches
Functional Resonance Magnetic Imaging (fMRI) has become in the recent years one of the most important imaging approaches in congitive neuroscience. The analysis of fMRI data is based mainly on mass-univariate analysis. However, univariate analysis have some limitations, as for instance activities in neighbouring voxels are treated as independend events.
In the last years, different pattern recognition techniques have been applied in the field of neuroimaging. Such soft-computing methods have the potential to circumvent the problems of conventional methods and could be intended as a useful supplement for analysis of fMRI data.
My research project focuses on the development and application of fmri pattern classification methods, which aim to recognize psychiatric disorders and can identify underlying processes.
