An internal model for predictive saccades in frontal cortex was investigated by recording neurons in monkey frontal eye field (FEF) during an inferred motion task. Monkeys were trained to make saccades to the extrapolated position of a small moving target that was rendered temporarily invisible and whose trajectory was altered. On approximately two-thirds of the trials, monkeys made multiple sa...

AbstractBackgroundline of treatment for management of hydrocephalus despite available new techniques andsystems of shunting. Associated complications should be recognized and managed properly,but the most recognized complications are shunt obstruction which its prevalencethrough surgical approach is discussed here. Two approaches (frontal and parietal) are usedto insert ventriculoperitoneal shu...

  Myxoid is a common type of liposarcoma. Cardiac metastasis of sarcoma is a rare diagnosis. Transthoracic echocardiography is a useful tool for beginning the diagnosis. Curative resection of metastasis and then combination systemic chemotherapy for advanced disease is recommended. We report a 50 year old woman who presented with a cardiac metastasis of high grade round cell liposarcoma to righ...

Renal cell carcinoma (RCC) metastasis to duodenum is very rare and only a few case reports are available in the literature. We here reported a patient with solitary duodenal metastasis presented with melena six years after right nephrectomy. The patient underwent upper gastrointestinal endoscopy showing ulcerative mass at the second portion of duodenum and biopsy of this mass was consistent wit...

Objective(s): The growing trend of research demonstrates that dynamic expression of two metastasis repressor classes (metastasis suppressor genes and anti-metastatic miRNA) has a close relationship with tumor invasion and metastasis. Using different strategies, it was revealed that cellular levels of miR-31 and Breast cancer Metastasis Suppressor1 (BRMS1) protein, whic...

solitary plasmocytoma is rarely located in the cranial vault. we report one case of solitary plasmacytoma of the skull and discuss the clinical features and treatment of this uncommon tumor in the light of the published cases. a 46-year-old moroccan male, without previous history consulted for a swelling in medial frontal and paramedian region. on clinical examination the clinical examination r...

One of the most important factors in drug addiction is stress. It has been shown that animals with prenatal stress history are more risky for drug dependence. It have also been shown that frontal cortex play a role in drug dependence. In the present study the effects of two kinds of mild stress during pregnancy on the development of frontal cortex in Wistar rats (250-300 g) were investigated. F...

A case of frontal sinusitis with osteomyelitis its posterior wall producing lobe brain abscess is presented, whereby the dehiscence was exposed by external sinostomy an ENT surgeon and then, through dehiscence, drained a neurosurgeon. This uncommon technique draining where no bone craniotomy required. approach yields least damage to cerebral tissue as very close sinus drain has travel minimal i...
