Functional transcranial Doppler sonography was used to study hemispheric language dominance (HLD) in 24 right-handed patients with left temporal lobe epilepsy (TLE) and a structural lesion in the left temporal lobe and in 69 healthy controls. Twenty-five percent of the patients and 4% of controls showed atypical (right or bilateral) HLD. Degree of HLD was(More)
Whole-cell patch clamp experiments were used to investigate the transduction mechanism of adenosine A(2A) receptors in modulating N-methyl-D-aspartate (NMDA)-induced currents in rat striatal brain slices. The A(2A) receptor agonist 2-p-(2-carboxyethyl)phenethylamino-5'-N-ethylcarboxamidoadenosine (CGS 21680) inhibited the NMDA, but not the(More)
Whole-cell patch clamp experiments were carried out in rat striatal brain slices. In a subset of striatal neurons (70–80%), NMDA-induced inward currents were inhibited by the adenosine AZA receptor selective agonist CGS 21680. The non-selective adenosine receptor antagonist 8-(p-sulphophenyl)-theophylline and the AZA receptor selective antagonist(More)
Report of a boy aged 17 years and review of the literature on the neoplasias of CAS. The cause of examination was a psychic maldevelopment. Cranial arteriography exhibited extreme wide Carotis communis and CT temporal meningioma right and septum pellucidum cyste. A psychic frontal lobe syndrome and cosmetic impairment by skull changes of the CAS are(More)
The significance of the complex clinical-radiological diagnosis is demonstrated in three cases of the Kümmel-Verneuil syndrome, the bone scintigraphy allows the demonstration and localisation of the bone process, but in respect to the differential diagnosis the results are unspecific. The CT allows an early and sure demonstration of the intravertebral(More)
The morphology and indications for performing post-operative contrast examinations have been analysed in 131 myelograms. Leptomeningeal reactions and adhesions were found in varying degrees of severity in 34 to 75% of post-operative cases; it proved difficult to correlate this finding with the neurological features. The value of repeat myelograms is much(More)
