The lack of legal support has not stopped companies like No Lie MRI and CEPHOS from offering private fMRI scans to test deception. There is potential to use fMRI evidence as a more advanced form of lie detection, particularly in identifying the regions of the brain involved in truth telling, deception, and false memories. [15]
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.
Some focus on the human brain, others on non-human. As the number of databases that seek to disseminate information about the structure, development and function of the brain has grown, so has the need to collate these resources themselves. As a result, there now exist databases of neuroscience databases, some of which reach over 3000 entries. [1]
Brain implants or neuromodulation (using electrical currents to alter brain activity) could represent the next wave of treatments, Schnakers said. She emphasized the need to provide families with ...
Zijiao Chen can read your mind, with a little help from powerful artificial intelligence and an fMRI machine. Chen, a doctoral student at the National University of Singapore, is part of a team of ...
Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.
This scan was part of the human organ atlas which has X-ray tomography scans of other organs in the human body with the same resolution. [ 3 ] [ 4 ] A crucial idea for magnetic resonance imaging is that the net magnetization vector can be moved by exposing the spin system to energy of a frequency equal to the energy difference between the spin ...
A new study from the Salk Institute for Biological Studies has identified a brain circuit that slows the breath to calm the mind.
