[Pathological changes in the central nervous system studied on the model of aluminum encephalopathy]. / Patologicheskie izmeneniia tsentral'noi nervnoi sistemy na modeli aliuminievoi éntsefalopatii.

Aluminum encephalopathy was formed in rabbits as a result of intraventricular administration of aluminum chloride. A study was made of changes in the neurological status, neuronal activity in the motor area of the cortex, electronystagmogram and neuronal structure in fields 4 and 17 of the cortex of large hemispheres. The animals demonstrated the worsening of olfaction, vision, audition, weakening of the reflexes of the craniocerebral nerves and motor reflexes. There was a decrease in spontaneous activity and irregularity of neuronal impulsation. Neurofibrillar degeneration in the neurons, vacuolization of the cytoplasm, swelling of the nucleus together with chromatolysis and ectopia of the nucleolus were recorded.

[Interaction of the vestibulo-oculomotor and visual systems in young animals]. / Osobennosti vzaimodeistviia vestibulo-glazodvigatel'noi i zritel'noi sistem u molodykh zhivotnykh.

In two-month old rabbits rotated with closed and opened eyes during 20 or 140 sec, it was found that the interaction of vestibulooculomotor and visual systems depended on maturity as well as on the duration of the simultaneous action of these systems. The nystagmus is organized by the optic stimulus which increases the duration of the nystagmus and decreases the postnystagmus, increases the number and amplitude of the eye jerks, aids to maturity of the vestibulooculomotor reflex and organizes the beginning of the nystagmus, increases the number of mature nystagmus the first jerks of which have got the highest amplitude.
