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
Pilatus (detector) Pilatus (detector) Pilatus is the name of a series of silicon pixel detectors developed at the Swiss Light Source, and commercialised by Dectris. The common factor is that X-rays are converted to an electrical signal by the photoelectric effect in silicon subject to a substantial bias voltage, and then counted directly by a series of cells in an ASIC bonded to the silicon detector, rather than relying on a phosphor. That is, each pixel has its own amplifier, discriminator (for distinguishing X-rays of the desired energy from noise) and counter circuit; this is possible because the desired pixel size for
