Lie detection the 'source'. To use an MRI as a lie detector, an fMRI should be used by placing a magnetic band as a scanner on a subject's head. However, the neurobiological systems that relate to lying are currently poorly understood. The current consensus is that faced with a forced choice paradigm, in which a subject has the choice of telling the truth or spontaneously generating a lie, lying can be distinguished due to increased prefrontal and parietal lobe activity. More specifically, the superior medial and inferolateral prefrontal cortices show net activation in the process of spontaneous lie generation (which involves suppression
Large-Area Neutron Detector Large-Area Neutron Detector The large-area neutron detector, also known as LAND, is the name of a detector of neutrons installed at GSI (Institute for Heavy Ion Research) in Arheilgen, close to the city of Darmstadt, Germany. The detector is built of 10 planes with 20 paddles each. The paddles have a size of 10x10x200cm and are composed of a converter (iron) and plastic scintillator material. Within the paddle the 5 mm thick converters serve as a dense target for neutrons leading to processes that eject charged particles through the process of hadronic showers. The interspersed 5mm plastic scintillator stripes produce
