[Dental receptor projections to the sensomotor zone of the rabbit cerebral cortex]. / Proektsiia dental'nykh retseptorov v sensomotornoi zone kory mozga krolika.

Topic organization of the dental representation was studied in experiments on rabbits by the method of induced potentials. Every tooth proved to be locally represented in the sensory-motor zone of the brain cortex. These zones do not overlap in the case of stimulation of the threshold strength. Topic dental projection region occupies a territory including fields Par I, Praecag, Preacgr, and PC.

[Immunochemical analysis of glial and neuronal fractions of rat brain]. / Immunokhimicheskii analiz fraktsii glii i neironov golovnogo mozga krys

A method of obtaining antineuronal and antiglial immune sera is described. Data of the quantitative immunochemical analysis of the antigens of the neuronal and glial fractions of the rat brain are presented. The neurons proved to contain 4, and the glia--3 brain-specific proteins; one or two of them are common for these cell fractions.

[Cerebral cholinesterase under conditions of a generalized convulsive seizure]. / Kholinésterazy mozga v usloviiakh generalizovannogo sudorozhnogo pristupa

The activity of acetylcholinesterase and butyrilcholinesterase was studied during prolonged seizures developing from a primary-cortical focus. The activity was found to spread both along the wide limbic system, which indicates to participation of cholinergic agents in processes of "recurrent generalization" of excitations, and along the horizontal system of fibers connecting both hemispheres. This latter finding indicates to participation of cholinergic mediatory mechanisms in formation of seizures.

[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.

[Effect of adrenergic compounds on the brain potentials evoked by stimulation of the dental pulp]. / Vliianie adrenergicheskikh soedinenii na potentsialy mozga, vyzvannye razdrazheniem pul'py zuba

Intraventriculare injections have brough evidence that alpha-adrenomimetic norepinephrine and beta-adrenomimetic isopropylnorepinephrine augment in the senso-motor region of the cortex the amplitude of primary responses evoked through a dental pulp stimulation. The alpha-adrenoblocking agents--dihydroergotoxin and phentolamine and the beta-edrenoblocking agent propranolol force down the amplitude of primary responses. The sphere of the drugs action is presumed to be the thalamic nuclei.
