The authors describe a fast method for estimating the elastance of the intracranial system in man. The method consists in constructing the so-called amplitude-pressure (Amp-P) curve which describes the relationship between the amplitude of pulse-related oscillations in cerebrospinal fluid pressure and the basic level of intracranial pressure. The Amp-P(More)
A new method of estimating intracranial decompensation in man is described. An on-line computer system is connected to an intracranial pressure (ICP) monitoring system to compute regression plots of mean ICP vs standard deviation; standard deviation is used as a measure of ICP instability. Two zones with distinctly different slopes are a characteristic(More)
The anatomical and functional characterization of neuronal assemblies (NAs) is a major challenge in neuroscience. Principal component analysis (PCA) is a widely used method for feature detection, however, when dealing with neuronal data analysis, its limitations have not yet been fully understood. Our work complements previous PCA studies which, in general,(More)
OBJECTIVE The hippocampus has an important role in the acquisition and recall of aversive memories. The objective of this study was to investigate the relationship among hippocampal rhythms. METHODS Microeletrodes arrays were implanted in the hippocampus of Wistar rats. The animals were trained and tested in a contextual fear conditioning task. The(More)
In 39 patients with intracranial lesions the resorption resistance was measured using an own computerized infusion test. A high usefulness of this test was demonstrated in the diagnosis of hydrocephalus and for establishing indications to ventriculocardiac valve implantation. In patients after craniocerebral injuries a rise was observed of the resorption(More)

Three patients are described, who were treated because of tumors of the medulla oblongata, growing towards the lumen of the IV ventricle and into the subarachnoid space. In two cases clinical cure was achieved after partial removal of the tumor and radiotherapy. One of these patients 32 years after the operation is working as a librarian, the other one(More)

On the basis of long-standing own experiences and the literature, the author subdivides the tumours mentioned in the title into two types. Type A (occurring most frequently): Developing in the transversal plane and the longitudinal axis; typical clinical signs on cerebral nerves, long pathways and cerebellar pathways. Choked papilla and signs of cerebral(More)
