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.
A PET scan found functional abnormalities in the visual, auditory, and somatosensory cortex, as well as in areas responsible for an integrated body schema. [ 44 ] One study examining EEG readings found frontal alpha wave overactivation and increased theta activity waves in the temporal region of the left hemisphere.
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 ...
Your brain accounts for only about 2% of your body weight, but it uses roughly 20% of your body’s total energy. Even when you’re sleeping , your brain is burning tons of energy just to keep ...
Schematic drawing of an elevated plus maze. The elevated plus maze (EPM) is a test measuring anxiety in laboratory animals that usually uses rodents as a screening test for putative anxiolytic or anxiogenic compounds and as a general research tool in neurobiological anxiety research such as PTSD and TBI.

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. An OBE is a form of autoscopy (literally "seeing self"), although this term is more commonly used to refer to the pathological condition of seeing a second self, or doppelgänger .
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 ...
