چکیده
Positron emission tomography (PET) was used to demonstrate temporary down-regulation of visual cortex activities associated with eye movements. The aim of the present study was to test this paradigrn with visual evoked potentials CVE?s) in the visual cortex of 7 healthy human subjects during caloric nystagmus. Caloric stimulation was perfbrmed by inigating the right or left extemal ear canals with 100ml of warm water at 44eC for 50s with a head position of 600 ti1ted backward in order to stimlllate the horizontal sernicircular canal. The subjects kept thelr eyes closed uring and after caloric stimulation. For recording the VEPts, the flachlight was used for aedvating the visual cortex with the subject's eyes closed. In the 7 subjects, no significant difference was detected between the VEPS induced with and without ealoric stimuliation

Cervical and ocular vestibular evoked myogenic potentials in multiple sclerosis participants
Background: Multiple sclerosis (MS) is a chronic neurological disease that affects brain and spinal cord. The infratentorial region contains the cerebellum and brainstem. Vestibular evoked myogenic potentials (VEMPs) are short-latency myogenic responses. Cervical vestibular evoked myogenic potential (cVEMP) is a manifestation of vestibulocolic reflex and ocular vestibular evoked myogenic pote...

متن کاملVestibular Evoked Myogenic Potential Produced by Bone-Conducted Stimuli: A Study on its Basics and Clinical Applications in Patients With Conductive and Sensorineural Hearing Loss and a Group With Vestibular Schawannoma
Introduction: Vestibular evoked myogenic potential (VEMP) has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC) stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients. ...

Background: Alzheimer dementia as the most common cause of dementia is a chronic, progressive, irreversible and incurable disease. The second most common cause of dementia after Alzheimer is vascular dementia. One of the systems involved in dementia is the visuospatial system and visual evoked potential (VEP) can be one of the diagnostic methods for this disease. Therefore, the present study ai...

Background: Visual evoked potential (VEP) is regarded as a useful, reliable and non-invasive technique for the diagnosis of lesions in the optic pathway. This technique was used to investigate visual function in migraine. Materials and Methods: 53 migraine patients (27 migraine cases with aura and 26 common migraine cases) and 55 controls were prospectively enrolled in this study. Visual ev...
