    Basics

    The central nervous system has a hard and a soft cover: the skull and the meninges (Figs. 3.1.1–3.1.4). The skull is divided into the neurocranium and the viscerocranium. The neurocranium encloses the brain, a...

    Design and application of sensor for recording sounds over human eye and nose

    The recording of sounds over the oribt of the eye has been found to be useful in the detection of intracranial aneurysms. A hydrophone for auscultation over the eye has been developed and is tested under contr...

    Noisy intracranial tumours

    Transorbital sound recordings were obtained from 21 patients with intracranial tumours, 28 patients with intracranial aneurysms and 20 control patients. The group of patients with tumours consisted of 12 patie...

    Tumours of the thalamic region

    Twenty seven patients with thalamic tumours were evaluated retrospectively in the Neurosurgical Clinic of the University Hospital in Groningen between 1969 and 1983. The diagnosis was based on neuroradiologica...

    Sympathetic dysfunction in patients with persistent pain after prolapsed disc surgery. A thermographic study

    Vasomotor function in the lower limbs was tested by means of thermography in 48 patients with and without residual complaints after surgery for a prolapsed intervertebral disc. There is a definite correlation ...

    Automatic method to detect and determine the preferential frequency of EMG signals from patients with pathological tremours

    The paper presents a special purpose automatic-detection method de veloped to determine whether a tremour EMG contains a tremour and to calculate its preferential frequency if a tremour is present. This method...

    Improvement of the detectability of simulated pathological tremour e.m.g.s by means of demodulation and spectral analysis

    In e.m.g.s recorded from patients with pathological tremours, the tremour cannot often be recognised by visual inspection. Demodulation of tremour e.m.g.s improves the detectability of the tremour, but the sig...

    Demodulation of e.m.g.s. of pathological tremours. Development and testing of a demodulator for clinical use

    In clinical tremour recordings, e.m. g. signals allow highly localised recordings to be made. This is in contrast to mechanical recordings which have been used extensively in the past. E.m.g. recordings make i...

    Some principles of postoperative epidural pressure monitoring

    A retrospective analysis is presented of 115 cerebral tumour cases where continuous epidural pressure (EDP) monitoring was carried out postoperatively using an implantable transducer constructed on a coplanar ...

    Regional cerebral blood flow in patients with subarachnoid haemorrhage

    With a multidetector scintillation camera regional cerebral blood flow, rCBF, was evaluated in 13 patients with subarachnoid haemorrhage. Mean CBF was subnormal, and there seems to be a relationship between CB...

    The Significance of ICP-Monitoring in the Post-Operative Period

    Monitoring intracranial pressure gives much important information concerning pathophysiology in patients in the post-operative period. From this monitoring we can learn how the intracranial situation in this p...
