Auditory brainstem response Top Latest Questions and Answers 2024

What are the various auditory evoked potentials? (5) - cochlear potential auditory brainstem response AMLR ALR endocochlear potential cochlear potentials (3) - summating potential cochlear microphonic compound action potential summating potential - a DC potential that appears during acoustic stimulation (OHC origin) cochlear microphonic - AC potential that mirrors the stimulus characteristics (OHC origin) compound action potential - synchronized response of the auditory nerve to an acoustic stimulus (Wave 1 on the ABR) scala media driving voltage - around 150 mV how do you get the scala medias driving voltages of 150 mV? - the hair cells have a voltage of -70 and the scala media has a +80 mV. That's how you get the 150 driving voltages electrical potential - the ability of an electric charge to do work in moving another charge, measured in volts. To measure a potential difference there must be a difference in charge between the two measurement locations. volt - Unit of energy equal to the work done in moving a charge of 1 electron through a potential difference of one volt. One volt produces one ampere of current in a resistance of one ohm evoked potentials are typically on the order of ____ - microVolts
