Neuroimaging comprises of several techniques to image the structre and the function of the brain. Structural imaging enables diagnosis of tumors and injuries of the nervous system while functional imaging enables direct visualization of brain centers when processing information. There are several techniques for neuroimaging; Computed axial tomography, diffuse optical imaging, magnetic resonance imaging, functional magnetic resonance imaging, event-related optical signal, magnetoencephalography, positron emission tomography and single-photon emission computed tomography. All these techniques use different approaches to examine brain activity and imaging. Neuroimaging enables scientist to carry out neurological examinations and deeply investigate the neurological disorders.
