Topography of saccadic eye movements evoked by microstimulation in rabbit cerebellar vermis.
1. We investigated saccadic eye movements elicited by microstimulation in the vermis of the rabbit. Scleral search coils were implanted under the conjunctiva of both eyes and a recording chamber was placed over the cerebellar vermis. 2. Conjugate saccadic eye movements were evoked in lobules VIa, b and c and VII of the vermis by currents ranging from 4 to 60 microA. All movements were horizonta...

Sir, Opsoclonus-myoclonus syndrome (OMS) is a rare but distinctive disorder, characterized by irregular, continual, and conjugated chaotic saccades of the eyes accompanied by appendicular myoclonus and truncal ataxia. No etiological factor can be found in 50% of adult cases. In 20% of cases it may be paraneoplastic and may also be a manifestation of brainstem stroke or infection. The most commo...
متن کاملHemorrhagic Epidermoid Cyst in Cerebellar Vermis.
Intracranial epidermoid cysts are usually located in the paramedian regions with characteristic imaging features. Intracystic hemorrhage is rarely reported with most in the cerebellopontine angle area. We described a case of hemorrhagic epidermoid cyst in cerebellar vermis. The patient was a 21-year-old male presenting with a first episode of convulsive seizure attack as the initial and sole sy...

متن کاملFamilial agenesis of the cerebellar vermis
SOME TWO YEARS AGO we investigated a child with profound psychomotor retardation who had had an occipital meningoencephalocele removed at birth. Contrast studies were carried out which showed a large midline defect in the posterior fossa and absence of the vermis. At the time we disregarded the nurses’ comments about the child’s abnormal breathing. A year later, Dr. P. P. Demers referred this p...
