#1
Which of the following describes Auditory Brainstem Response (ABR)?
It measures the electrical activity in the auditory nerve and brainstem in response to sound.
ExplanationMeasures electrical activity in auditory nerve and brainstem.
#2
What is the main difference between Auditory Brainstem Response (ABR) and Evoked Cortical Potentials (ECoG)?
ABR measures brainstem activity, while ECoG measures cortical activity.
