[The role of local cerebral mechanisms in the pathology of autonomic functions]. / Rol' lokal'nykh tserebral'nykh mekhanizmov v patologii vegetativnykh funktsii.

Heart rhythm was subjected to mathematical analysis in patients of neurosurgical department. The data allowed to make conclusions on the role of the level and lateralization of lesions in autonomic pathology. Right hemisphere and brainstem were shown to have a major impact on the baseline autonomic tone and its regulation. Autonomic supply to actions is ensured by rhinencephalic structures of both left and right hemispheres. The data are valuable for neurology as criteria of topic diagnosis when lateralization of lesions should be clarified.

[Heart rhythm in cardiovascular disorders of neurotic origin]. / Ritm serdtsa pri kardiovaskuliarnykh narusheniiakh nevroticheskogo geneza.

Cardiac rhythm (CR) and vegetative parameters at rest and after a series of short-term loads were compared in normal subjects and neurotic patients with the cardiologic syndrome (group 1) and those with vegetovascular crisis (Group 2). At rest, second-group patients demonstrated the best CR stabilization (by sigma R-R), with the CR oscillation pattern respiratory constituent (RC) diminished and its slow-wave (SW2) constituent prevailing as well as the highest arterial BP and intrasystemic dissociations (the Kërdo index). First-group patients showed the greatest sigma R-R, with the SW2 prevailing in the presence of a greater RC contribution, as compared to group 2 patients. Different patterns of post-exercise change were demonstrated: normal subjects showed increased heart rate, BP and sigma R-R, with doubled SW1 contribution, reduced SW2 and unchanged RC, an evidence of sympathetic mobilization in the presence of vagal pacemaker effects. In second-group patients, heart rate and BP were reduced, the contribution of SW2 increased, and that of SW1 and RC diminished, while the initial CR stabilization by the sigma R-R remained unchanged. Inter-systemic dissociations were demonstrated, using the Hildebrandt index; this combination signals overstrain of the controlling mechanisms, growing centralization of CR control and disadaptation. In first-group patients, BP rose, heart rate and sigma R-R declined, while the CR oscillation pattern remained basically unchanged, suggesting a rigidity of the central adaptation mechanisms.

[Mnestic defect characteristics in lesions of the left and right cerebral hemispheres]. / Osobennosti mnesticheskogo defekta pri porazhenii pravogo i levogo polusharii mozga.

The report contains some results of an experimental psychological study of memory in 144 patients with lesions of the right and left temporal lobes and in 25 patients with parkinsonism, who had undergone stereotaxic operations on the nuclear structures of the thalamus for dominant and subdominant speech of the brain hemisphere. For control purposes 88 normals were studied. The achieved results were subjected to a statistical and correlational analysis done on a computer "Minsk-20". The results of such studies demonstrated certain differences in these groups. These differences were expressed both in a quantitative character of reproduction and in a qualitative structure in the memory defect, which was connected with a different representation of correlational bonds between the indices of reproduction as well as with the role of the right and left temporal lobes in the formation of memory dependence on the probability prognosis.
