EPPP Sample Questions – Neuropsychology Written Exam. A. The Magnetic Resonance Imaging (MRI) and CAT (Computerized Axial Tomography) or CT scan, take a series of images at different levels of the brain giving information and a direct visualization of structures and features. The MRI does this with magnetic fields; the CAT scan uses x-rays. In general, the MRI provides more detail than the CAT scan and can be used in examining the central nervous system, as well as, used to identify tum...

A single unit is defined as a single, firing neuron whose spike potentials are distinctly isolated by a recording microelectrode. The ability to record signals from neurons is centered around the electric current flow through the neuron. - Answer-single unit recording? Are lesion techniques primarily anatomical or functional? - Answer-We can't use temporal resolution because weoften times do not have a before or after Be able to identify typical data presentations of the techniques listed ...

Nuclear magnetic resonance. - Answer Magnetic Resonance Imaging is derived from the process known as: Magnetic field, proton, radio-wave - Answer On a very basic level, the three basic components required to attain MR signals are: Superior soft-tissue contrast resolution. - Answer In comparison to Computed Axial Tomography, an advantage of MRI is: Special and costly site planning and shielding. - Answer In comparison to Computed Axial Tomography, a disadvantage of MRI is: Iron, cobal...

MRSO PREP EXAM WITH ALL CORRECT ANSWERS.docx Zero Boil-Off - Answer-System that reduces/eliminates the need to recharge Helium in a magnet. Quench - Answer-Quickly eliminating the magnetic field. Not immediate, takes 3 to 5 minutes to completely eliminate magnetic field. Loud Noise as Helium rushes out of Quench Vent. Can cause crack in the wire (very costly to repair/replace). Ohm's Law - Answer-Resistance that is equal to Voltage divided by the amperage in a wire. V=IR U...

Bill Nye Magnetism Questions and Answers | 2024/2025 | Graded A+ What is magnetism? Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects. How do magnets work? Magnets produce a magnetic field that attracts or repels other magnets and magnetic materials, such as iron, due to the alignment of their atomic structure. What are the two poles of a magnet? A magnet has a north pole and a south pole, and...
