    Pathophysiological Studies in the Rat Cerebral Embolization Model: Measurement of Epidural Pressure and Evaluation of Tissue pH and ATP

    A rat embolization model was produced by occlusion of the main cerebral artery with a silicone cylinder embolus. Intracranial pressure was monitored by changes in epidural pressure (EDP), which was recorded by...

    Statistical Analysis of Changes in Topographic EEG on Brain Tumor Cases with Peritumoral Edema

    EEG is one of the best methods for estimating brain function. Topographic EEG is made by analyzing the power spectrum of EEG as equivalent potential (EP). In this study, the changes in topographic EEG after gl...
