Purkinje cells in the flocculus and ventral paraflocculus were studied in tasks designed to distinguish predictive versus visually guided mechanisms of smooth pursuit. A sum-of-sines task allowed studies of complex predictive pursuit. A perturbation task examined visually driven pursuit during unpredictable right-angle changes in target direction. A gap task examined pursuit that was maintained...

The nodulus and ventral uvula (NU) of the cerebellum play a major role in vestibular function in humans and experimental animals; however, there is almost no information about NU function in the veterinary clinical literature. In this report, we describe three canine cases diagnosed with presumptive NU hypoplasia. Of them, one adult dog presented with cervical intervertebral disk disease, and t...

In this case report, we describe an extraosseous chordoma in the coccygeal region that later metastasized to the cerebellum. A 30-year-old man presented with a progressively enlarged lesion in the coccygeal region with painful sensation. Preoperative computed tomography and magnetic resonance imaging showed a large lobular mass in the coccygeal region without sacrococcygeal destruction. Patholo...

conclusions the stereotactic brachytherapy for patients with circumscribed and relatively small size tumors appears to be a safe, feasible, and minimally-invasive treatment. results thirteen patients were male and 16 were female, with the median age of 29 years (range, 2.5 – 64 years). the median follow-up was 95 (range, 6 – 240) months. based on pignatti classification, 10 patients were at low...

Pilocytic atrocytoma(PA) is a World health organization (WHO) grade I astrocytoma. It most commonly develops during first two decades of life with predilection for infratentorial region. The tumor shows a favorable behavior and patients usually have excellent long term improvement. Histologic progression and features of anaplasia is a rare event in pilocytic astrocytomas and is commonly seen wi...
