Practical Guide for Clinical Neurophysiologic Testing EEG -CLTM study guide Question and answers correctly solved 2024 Iron - correct answer Which metal is not commonly used in making EEG electrodes? Impediance - correct answer the resistance against alternating current flow Nasopharyngeal electrodes (PG1 & PG2) - correct answer electrodes placed through the nasal passage inferior-medial temporal cortex - correct answer Where are Nasopharyngeal electrodes good for detecting activity? Left side - correct answer In the 10-20 system, odd numbers refer to Cz and C3 - correct answer in the expanded 10-20 system (Modified combinatorial nomenclature), an electrode named C1 would be placed mid-distance between Differential amplifier - correct answer What type of amplifier amplifies the difference in voltage between 2 inputs? Up - correct answer If Input 1 is more negative than Input 2, the deflection of the waveform with be 0 uV - correct answer If both Input 1 and Input 2 are -20uV, then the result will be balanced amplifier - correct answer common mode rejection ratio (CMRR) is closely related to V=SxH, H=V/S, S=V/H - correct answer what are the correct formulas to calculate voltage related problems? (S=sensitivity, V=volt, H=measured height) 12 mm - correct answer If the vertical scale (sensitivity) is 5uV/mm, then a 60 uV wave will measure?
