In general, there have been two types of intelligence studies: psychometric and biological. Biological approaches make use of neuroimaging techniques and examine brain function. Psychometrics focuses on mental abilities. Ian Deary and associates suggest that a greater overlap of these techniques will reveal new findings. [3]
The disciplines within which these methods are used is quite broad, ranging from psychology to neuroscience to biomedical engineering to sociology. The following is a list of neuroimaging methods: Electroencephalography (EEG) Quantitative electroencephalography (QEEG) Stereoelectroencephalography (SEEG) Functional magnetic resonance imaging (fMRI)
Neuroimaging is the use of quantitative (computational) techniques to study the structure and function of the central nervous system, developed as an objective way of scientifically studying the healthy human brain in a non-invasive manner. Increasingly it is also being used for quantitative research studies of brain disease and psychiatric ...
FreeSurfer – Brain imaging software package; Functional integration (neurobiology) – Study of cooperation of brain regions to process information; Magnetoencephalography – Mapping brain activity by recording magnetic fields produced by currents in the brain; Mental event – Any event that happens within the mind of a conscious individual
Neuroimaging – Set of techniques to measure and visualize aspects of the nervous system; Neuropsychology – Study of the brain related to specific psychological processes and behaviors; Neuropsychological assessment – Testing to identify brain impairments, their severity & location
Xenon computed tomography is a modern scanning technique that reveals the flow of blood to the areas of the brain. The scan tests for consistent and sufficient blood flow to all areas of the brain by having patients breathe in xenon gas, a contrast agent, to show the areas of high and low blood flow. Although many trial scans and tests were ran ...
Of specific interest is using structural and functional magnetic resonance imaging (fMRI), diffusion MRI (dMRI), magnetoencephalography (MEG), electroencephalography , positron emission tomography (PET), Near-infrared spectroscopy (NIRS) and other non-invasive scanning techniques to map anatomy, physiology, perfusion, function and phenotypes of ...
Brain-reading or thought identification uses the responses of multiple voxels in the brain evoked by stimulus then detected by fMRI in order to decode the original stimulus. Advances in research have made this possible by using human neuroimaging to decode a person's conscious experience based on non-invasive measurements of an individual's ...
