Practice questions
- In the post-mortem CNS examination described in the congenital brainstem dysgenesis report, neuronal depletion was identified in which set of cranial-nerve nuclei?
- A patient with congenital hypotonia, facial diplegia, velopharyngeal incoordination, pyramidal signs, and ocular motor apraxia has a pattern resembling the syndrome in the five-patient report. Which level of dysfunction did electrophysiological studies indicate?
- Which statement most accurately describes the cerebral hemispheres in the post-mortem examination reported for congenital brainstem dysgenesis?
- In the congenital brainstem dysgenesis report, which cause was considered most likely by the authors?
- Which long-term observation was reported in the five patients with congenital brainstem dysgenesis?
- Which feature best characterizes intravascular large B-cell lymphoma as described in the cranial-neuropathology case report?
- At post-mortem examination in the reported IVLBCL case, tumor-filled vessels and ischemic lesions were found across which broad set of regions?
- Which set of brainstem structures was specifically identified as involved in the IVLBCL histopathology report?
- Which cranial-nerve trunks contained vessels affected by IVLBCL in the reported histopathological case?
- A patient with rapidly progressive IVLBCL has diplopia, dysphonia, and asymmetric palatal movement. Which interpretation is most consistent with the reported case?
- In the fMRI comparison of swallowing and occlusion, which brainstem activation correspondence was reported?
- In the direct fMRI comparison, how did swallowing-related neural recruitment differ from that for occlusion when effort was controlled?
- Which approach did the fMRI study use to control for effort when comparing swallowing with occlusion?
- The primary motor cortex activation peaks for swallowing and occlusion were described as approximately how far apart?
- Which conclusion is best supported by the fMRI comparison of swallowing and occlusion?
- Which group of regions was included among the increased activation sites reported for swallowing in the direct comparison?
- A functional imaging study shows activation during a behavior. Which inference is most cautious and consistent with the swallowing–occlusion fMRI report?
