Ependymomas are tumors that arise from specialized glia called ependymal cells, which line the central cerebral spinal fluid (CSF) containing spaces within the brain and spinal cord called the ventricles and central canal, respectively. When ependymomas occur in the spinal cord, their central location requires that the surgeon cut through the spinal cord in order... Continue Reading →
Vascular brain lesions have increased risk of intracranial bleeding and, therefore, present a challenge to neurosurgeons attempting surgical resection. Such tumors may first be embolized prior to surgical excision in order to reduce the risk of bleeding. Onyx, an ethylene vinyl alcohol copolymer, is one of many embolic agents available to accomplish this task. Onyx has... Continue Reading →
The hippocampus is critical to learning and memory.
