Electrophysiology Exam Questions &
Answers (Grade A+)
What is a compound nerve action potential? -
correct answer ✅The combined traveling depolarization of many
neuronal axons
What are the characteristics of a stationary potential? -
correct answer ✅All of the above (Amplitude depends on distance
of recording from the generator, Latency is fixed, independent of
location of recording, Often produced by cell bodies or synapses)
How does temporal summation activate a neuron? -
correct answer ✅Multiple post synaptic potentials over time
What is PCT? -
correct answer ✅Conduction time of the peripheral portion of the
nervous pathway
What is CCT? -
correct answer ✅Conduction time of the central portion of the
nervous pathway
What is the relationship of cortical SSEP amplitude to stimulus
frequency? -
, Electrophysiology Exam Questions &
Answers (Grade A+)
correct answer ✅Amplitude decreases as stimulus frequency
increases
What is the relationship of SSEP amplitude vs. intensity? -
correct answer ✅All of the above (SSEPs are absent until threshold
intensity is reached, Amplitude increases with intensity above
threshold until a maximal amplitude is reached, Supramaximal
stimulation does not further increase amplitude above maximal
levels)
What are the two primary clinically measured and interpreted
components of evoked potential waveforms? -
correct answer ✅Amplitude and latency
What are three primary components of stimulation? -
correct answer ✅Intensity, duration, frequency
What is the supra-maximal stimulation paradigm? -
correct answer ✅Stimulation is at a level at which waveform
amplitude no longer increases; thus amplitude criteria are applied
