Neuropsychology, as well as cognitive neuroscience investigates the process of human cognition using several in vivo systemic approaches in order to explore neural mechanism. Besides the routine clinical neuropsychological assessments, up to date the latest neuroimaging techniques based on acoustics, optics, electricity and magnetism, have been applied to construct three-dimensional neuroimaging representations through mathematic models, and to identify functional areas or lesions in the brain. Presently, the combined use of functional MRI (fMRI) and event related potential (ERP) techniques is pioneering, especially when integrated synchronously.
