[Visual evoked potentials in patients with trigeminal neuralgia]. / Zritel'nye vyzvannye potentsialy u bol'nykh nevralgiei troinichnogo nerva.

Data characterizing visual evoked potentials in neuralgia of the trigeminal nerve are presented. In contrast to healthy individuals, patients with this kind of neuralgia displayed a well pronounced character of early and late components of evoked potentials not only in the occipital but also in the central regions. Other features characteristic of their potentials were a hypersynchronous post-discharge and the presence of peaks. All these findings suggest the resemblance between the central mechanisms of neuralgia of the trigeminal nerve and those of epilepsy.

[The role of subcortical structures in the formation of a chronic cortical epileptogenic focus]. / Rol' podkorkovykh obrazovanii v formirovanii korkovogo khronischeskogo épileptogennogo ochaga

The authors studied the significance in the "maturation" of the cortical chronic experimental epileptogenic focus. The studies were conducted in rabbits with the use of registration methods of a summarized bioelectric activity and activation of subcortical formation by electric current. It was established that the activation of inhibitory structures in the preconvulsive period facilitated the inhibition of "maturation" of the initial-cortical epileptogenic focus and an easier development of the convulsive attack in comparison with the control group (without stimulation of subcortical nuclei), while the activation of generalizing formations lead to more severe convulsive attacks.
