As "Prospects of fMRI as a Lie Detector" [9] states, fMRIs use electromagnets to create pulse sequences in the cells of the brain. The fMRI scanner then detects the different pulses and fields that are used to distinguish tissue structures and the distinction between layers of the brain, matter type, and the ability to see growths.
The resulting IQ standard score is the subject of much investigation as psychologists check correlations between IQ and other life outcomes. The Wechsler IQ tests for adults and for children have long been regarded as the "gold standard" in IQ testing. [1] fMRI data showing regions of activation
Critiques of this technique point out that fMRI does not actually measure lying, only the increased brain activity that occurs when one is lying. Using fMRI for lie detection could then lead to false positives produced by anxiety or other causes. [13] Another concern is that a "lie" is not always clear-cut, and may be a complex concept.
An out-of-body experience (OBE or sometimes OOBE) is a phenomenon in which a person perceives the world as if from a location outside their physical body.

Neuropsychological tests are specifically designed tasks that are used to measure a psychological function known to be linked to a particular brain structure or pathway. [1] Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits.
Cranial ultrasound is a technique for scanning the brain using high-frequency sound waves. It is used almost exclusively in babies because their fontanelle (the soft spot on the skull) provides an "acoustic window". A different form of ultrasound-based brain scanning, transcranial Doppler, can be used in any age group.
Aaron T. Beck et al. (1988) combined three separate anxiety questionnaires, with 86 original items, to derive the BAI: the Anxiety Checklist, the Physician's Desk Reference Checklist, and the Situational Anxiety Checklist. [2] The BAI is used for measuring the severity of anxiety in adolescents and adults ages 17 and older.
