Abstract

Modeling effective connectivity in the brain is always a task limited by the size of the model intended and data required for training. In recent years, however, advances have been achieved with MRI equipment able to obtain images with better signal to noise ratio, tissue contrast and spatial/spectral resolution, such as the 7 tesla MRI equipment at the University of Pittsburgh. Furthermore, many effective connectivity studies started to employ multimodal techniques, integrating knowledge and data from many different types of images; as for example, the use of DTI helping fMRI analysis. Therefore, in the present project, Dynamic Bayesian Networks (DBNs) with higher dimensions will be learned given these more abundant data and multimodal techniques obtained at the radiology facility at the University of Pittsburgh, which will on their turn provide new findings about the human brain.
