CLTM Study Questions And 100% Correct AnswersBAEP / R - ANSWER Brainstem auditory evoked potential / response
-Diagnosis for cerbellopontine angle tumors, mutliple sclerosis, brainstem lesions,
metabolic and toxic encephalopathies,brain death, and early prediction of outcome in
postraumatic coma,
Kindling - ANSWER Development of epileptic seizures (in rats) that results from
repeated focal stimulation and leads to the development of a predisposition to
epileptiform convulsions. Similar to a log will not burn unless it's kindled.
Mirror Focus Phenomenon - ANSWER Concept that an actively discharging epileptiform
region may induce paroxymal behavior in a homologous site. Related to the kindling
phenomena that occur through interhemispheric callosal or commissural connections.
It means that secondary epileptogenic foci develop in the contralateral hemispheric by
the corpus collusum

This indicates: - ANSWER The reflex is positive, brainstem function is present

Cold caloric testing No eye movement results from instillation of cold water into the ear
canal. This indicates that: - ANSWER The reflex is absent, brainstem function (pon,
