Estela Camara & Josep Marco-Pallarés & Thomas F. Münte & Antoni Rodríguez-Fornells
Neuroimaging analysis II: Magnetic resonance imaging Cognitive processes are widely distributed across the whole brain, involving interacting and overlapping brain regions. Magnetic resonance imaging (MRI) provides a non-invasive, in vivo , quantitative measurement of psycho-physiologically relevant parameters that are related to cognitive operations in the normal and abnormal brain. The combination of sophisticated experimental designs and powerful statistical analysis of MRI signals has become a powerful remarkably useful tool for cognitive neuroscience and psychology. The present chapter tries to give an overview of the main statistical tools used in structural and functional MRI analysis. In addition, we will also consider the analysis (preprocessing) and treatment of magnetic resonance images. While the following sections are restricted to MRI, certain points discussed below can also be applied to other neuroimaging techniques like positron emission tomography (PET). While the electroencephalography (EEG) section in Chapter 28 is focused on the temporal properties of structural ...
