___ clicks help resolve wave V of the BAEP - Condensation 60 HZ filters cause a change of latency by a: - a. phase shift 60. Reduction of the high frequency filter: - c. Increases evoked potential latency A "ground loop" is created when: - Two separate devices are attached to the same patient and have two separate grounding connections A BAEP reveals an interpeak latency of 2ms between waves I and III and an interpeak latency of 3.57 between waves III and V. Subsequently MRI detects a lesion - Between the pons and the upper brainstem (waves 1 and 2 are from the 8th nerve, while wave 3 is from the lower pons (cochlear nucleus), 4 is from the mid pons (superior olive), and 5 is the midbrain (lateral lemniscus and/or inferior colliculus)) A constant current stimulator - c. Varies the output voltage in order to maintain a certain current level A goal of intraoperative monitoring of the sensory pathways is to: - d) Detect abnormalities (electrophysiologic changes) that develop as the recordings are taken A grounding device must be available so that under normal conditions no voltage greater than ______________ is measured across an impedance of 1000 ohms: - 20 mV ms at 60 Hz A highly malignant tumor primarily seen in children may be: - d. Astrocytoma
