Exam Preview for 40915: The Use of EEG Biomarkers to Understand Cor

The Use of EEG Biomarkers to Understand Cortical-Vestibular Interactions, in partnership with Vanderbilt University

Please note: exam questions are subject to change.

1. Which cortical region is most commonly known as a sensory relay station? Occipital cortex Hippocampus Prefrontal cortex Thalamus
2. Alpha suppression observed during caloric vestibular stimulation is believed to reflect which of the following? Peripheral damage to the semicircular canals Cortical engagement with incoming vestibular input EEG artifacts from eye movements Increased beta synchronization
3. Which EEG frequency band is typically associated with the “idling” state of the brain, but has more recently been described as an active and dynamic cortical processor? Delta Theta Alpha Gamma
4. In patients with traumatic brain injury, cortical vestibular impairments are often manifested by which of the following? Peripheral nystagmus only Altered self-motion perception and postural instability Horizontal semicircular canal dysfunction Loss of cochlear function
5. Which of the following best describes the primary advantage of EEG for studying the vestibular system? Direct measure of electrical brain activity with high temporal precision High spatial resolution Ability to stimulate specific semicircular canals Direct measure of myogenic activation
