These modern brain imaging techniques enable doctors to map out the regions and functions of your brain in a non-invasive way.
Neuroimaging—or brain scanning—includes the use of various techniques to either directly or indirectly image the structure, function, or pharmacology of the brain. Brain imaging methods allow neuroscientists to see inside the living brain.
Neuroimaging, or brain scanning, produces images of the brain or other parts of the nervous system. Current neuroimaging techniques typically show the brain’s structure and functions.
Three different neuroimaging techniques, EEG, MRI, and PET, allow us to explore and measure the insane amounts of activity going on in our brain; however, each comes with its own strengths and limitations, making the motivations behind using them very important. The Electroencephalogram (EEG)
Neuroimaging falls into two broad categories: Structural imaging, which is used to quantify brain structure using e.g., voxel-based morphometry. Functional imaging, which is used to study brain function, often using fMRI and other techniques such as PET and MEG (see below).
This paper provides an overview of brain imaging techniques, with an emphasis on functional MRI and EEG, and their applications in studying human decision-making. With its rapid development and wide applications, brain imaging has profoundly changed the landscape of cognitive neuroscience research.
Researchers use a variety of neuroimaging tools to study the brain. Computed tomography (CT) scans are oblique X-ray slices that show the density of brain structures. Magnetic resonance imaging (MRI) uses changes in electrically charged molecules in a magnetic field to form images of the brain.
