[Healthy person's cerebral reactions to the rhythmic transcranial magnetic stimulation of different intensity].

At 8 healthy examinees-volunteers of 22-25 years the functional effects of super-threshold (above 1.2 T) and subthreshold (70-80% of a motor threshold) rTMS of premotor cortexes medial departments were compared. Functional brain activity changes were estimated (before and 1 hour after stimulation) by comparing data including neuropsychological testing, visual and spectral-coherent EEG-analysis, and also haemodynamic parameters.

[The use of sodium nitroprusside in the anesthesiological support of cerebral angiography].

Complex study of the effect of sodium nitroprusside intra-arterial and intravenous infusion under local and general anesthesia on the cerebral, peripheral, and general hemodynamics during cerebral angiography was carried out in 43 patients with neurosurgical pathology (17 females and 26 males from 17 to 58 years of age). The authors proved the efficacy of intraarterial and, to a lesser measure, of intravenous sodium nitroprusside infusion in relieving spasm of the cerebral arteries developing during cerebral angiography.

[Disorders of motor functions after removal of parasagittal meningiomas].

Specific features of motor activity disorders were studied in 87 patients before and after removal of a parasagittal meningioma. Motor disorders are most severe in localization of the tumor in the region of the middle third of the superior sagittal sinus and falx and less severe when the tumor is found in the posterior parts of the anterior third of the superior sagittal sinus. The disorders are more marked after operation with extensive resection of areas of the superior sagittal sinus involves in the tumor and with occlusion of the formed venous drainage passages.
