EEG BOARD PREP 2025 EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS VERIFIED Practice questions for this set Terms in this set (169) The EEG amplifier is designed so that when input 1 is more negative than input 2, the deflection will be UPWARD Common Mode Rejection the characteristic of an amplifier that rejects external interference WHICH OF THE FOLLOWING IS MOST ATTENUATED BY A LOW FREQUENCY FILTER OF 1HZ 0.1 HZ TIME CONSTANT IS DEFINED AS THE TIME REQUIRED TO... FOR THE DEFLECTION TO FALL (DECAY) TO 67% OF THE PEAK DEFLECTION An EEG record has 3/sec spike & wave discharges. Both the spike and the slow wave have voltages of 100uV. If this discharge is recorded with a LFF of 5Hz and a sensitivity of 10uV/mm, what would be the deflection of the spike and the wave? a. spike 10mm & wave 6mm b. spike 6mm & wave 10mm c. spike 10mm & wave 10mm d. spike 6mm & wave 6mm SPIKE 10MM, WAVE 6MM A HIGH FREQUENCY SETTING OF 35HZ WOULD ATTENUATE 50HZ MUSCLE ACTIVITY BY APPROXIMATELY WHAT PERCENTAGE? 40% ACCORDING TO ACNS GUIDELINES, RECORDING CLINICAL EEG ON DIGITAL MEDIA REQUIRES MONITORS TO HAVE WHAT BETWEEN 25 AND 35MM/SECOND HORIZONTAL SCALING AND A MINIMUM OF 100 DATA POINTS/SECOND TO ACCURATELY DISPLAY EEG ON THE MONITOR SCREEN IN A RECORD WITH 10HZ ALPHA ACTIVITY. WHEN THE DISPLAY EPOCH IS CHANGED FROM 10 SECONDS PER DISPLAY SCREEN TO 20 SECONDS PER DISPLAY SCREEN, THE FREQUENCY OF THE ACITIVTY WILL BE WHAT? 10HZ GUIDELINES FOR RECORDING DIGITAL EEG ARE WRITTEN BY WHO? THE AMERICAN CLINICAL NEUROPHYSIOLOGY SOCIETY (ACNS) THE TERM RAM MEANS WHAT TEMPORARY MEMORY STORAGE THAT IS CRITICAL TO RAPID COMPUTER OPERATIONS THE ELECTRODE SITE THAT IS LOCATED 1CM ABOVE, ONE THIRD THE DISTANCE OUT FROM THE LEFT EXTERNAL AUDITORY MEATUS TOWARDS THE LEFT OUTER CANTHUS IS CALLED WHAT T1 OR F9 Due to a central scalp lesion, C4 has to be relocated 4mm anteriorly. The technologist should: a. relocate C3 4mm anteriorly b. make no other placement changes c. relocate P3 4mm anteriorly d. relocate all electrodes in the right parasagittal plane 4mm anteriorly A. RELOCATE C3 4MM ANTERIORLY IN A REFERENTIAL MONTAGE, HOW IS THE ORIGIN OF THE POTENTIAL DETERMINED? AMPLITUDE WHEN RECORDING FOR ECI, INTERELECTRODE IMPEDANCES SHOULD BE AT LEAST OHMS, BUT LESS THAN _ OHMS. 100----10,000 WHEN RECORDING FOR ECI, IT IS RECOMMENDED THAT THE SENSITIVITY BE uV/MM AND THE LOW FILTER SHOULD NOT BE HIGHER THAN HZ. FOR AT LEAST MINS OF RECORDING. 2uV, 1.0HZ, 30 MINS THE TRACTS CONNECTING THE RIGHT AND LEFT HEMISPHERES ARE CALLED WHAT? CORPUS CALLOSUM THE CENTRAL SULCUS (FISSURE OF ROLANDO) DEMARCATES WHAT? FRONTAL AND PARIETAL LOBES THE TRIGEMINAL NERVE DOES? IS THE MAJOR SENSORY NERVE OF THE FACE
