  2. Resting state fMRI - Wikipedia

    en.wikipedia.org/wiki/Resting_state_fMRI

    Resting state fMRI (rs-fMRI or R-fMRI), also referred to as task-independent fMRI or task-free fMRI, is a method of functional magnetic resonance imaging (fMRI) that is used in brain mapping to evaluate regional interactions that occur in a resting or task-negative state, when an explicit task is not being performed.

  3. Functional magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Functional_magnetic...

    Heat causes electrons to move around and distort the current in the fMRI detector, producing thermal noise. Thermal noise rises with the temperature. It also depends on the range of frequencies detected by the receiver coil and its electrical resistance. It affects all voxels similarly, independent of anatomy. [56]

    Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...

  5. Five Minutes of Heaven - Wikipedia

    en.wikipedia.org/wiki/Five_Minutes_of_Heaven

    Five Minutes of Heaven is a 2009 film directed by Oliver Hirschbiegel from a script by Guy Hibbert. The film premiered on 19 January 2009 at the 25th Sundance Film Festival [ 2 ] where it won the World Cinema Dramatic Directing Award for Hirschbiegel, and the World Cinema Screenwriting Award for Hibbert. [ 3 ]

  6. Electromagnetically induced acoustic noise - Wikipedia

    en.wikipedia.org/wiki/Electromagnetically...

    The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.

  7. NASA offers explanation for bizarre 'trumpet noise' phenomena

    Now NASA is stepping in to provide some insight into what could actually be causing this scary pattern. NASA scientists believe the ominous noises could potentially be the "background noise" of ...

  8. Blood-oxygenation-level–dependent imaging - Wikipedia

    en.wikipedia.org/wiki/Blood-oxygenation-level...

    Blood-oxygenation-level–dependent imaging, or BOLD-contrast imaging, is a method used in functional magnetic resonance imaging (fMRI) to observe different areas of the brain or other organs, which are found to be active at any given time. [1] [2]

  9. Brain-reading - Wikipedia

    en.wikipedia.org/wiki/Brain-reading

    Brain-reading or thought identification uses the responses of multiple voxels in the brain evoked by stimulus then detected by fMRI in order to decode the original stimulus. . Advances in research have made this possible by using human neuroimaging to decode a person's conscious experience based on non-invasive measurements of an individual's brain activit
