[Interhemispheric transmission of visual information: behavioral and electrophysiologic aspects]. / Mezhpolusharnaia peredacha zritel'noi informatsii: povedencheskii i élektrofiziologicheskii aspekty.

Efficiency of callosal and extracallosal channels of interhemispheric transfer of visual information was studied by behavioural and electrophysiological methods on cats with sections of classical and commissural pathways of the visual system. The results showed a high ability of the operated animals to form conditioned defensive reflex to visual stimuli. The primary complexes of evoked potentials to light flashes in the projection cortex of both hemispheres were also preserved. The data show the significant role of the callosal and extracallosal pathways of the transmission of visual information across the midline.

[Compensation of anisocoria in cats following transection of the optic tract: the role of subcortical commissures]. / Kompensatsiia anizokorii u koshek posle pererezki opticheskogo trakta: rol' podkorkovykh komissur.

Experiments were carried out on cats with unilateral optic tract transection and cerebral commissures. The data obtained indicate that destruction of the afferent part of the pupillary reflex by optic transection led to reversible anisocoria. In cats with combined transection of the optic tract and teleencephalic, diencephalic and mesencephalic commissures, such a rehabilitation did not occur. In contrast, section of telencephalic commissures alone was immaterial for the processes of compensation of papillary system function. The data obtained attest to an important role of subcortical commissures in compensation of anisocoria after destruction of the afferent arc of the papillary reflex to light.

[Commissural mechanisms of restoring visual functions]. / Komissural'nye mekhanizmy vosstanovleniia zritel'nykh funktsii.

The perimetric studies were carried out in adult cats with reduced classical and commissural visual pathways. The data obtained indicate substantial recovery of the temporal visual fields in cats with unilateral optic tract transection during one year after operation. The animals with combined optic tract and cerebral commissural transection did not demonstrate any remarkable restitution of visual fields. These findings allow the conclusion about the primary role of cerebral commissures in the compensatory mechanisms of visual functions after visual tract injury.

[Compensatory restoration of function in cats following resection of the somatosensory pathways: role of the cerebral commissures]. / Kompensatornoe vosstanovlenie funktsii u koshek posle pererezki somatosensornykh putei: rol' mozgovykh komissur.

Experiments were carried out on cats with different transections of the classical somatosensory pathways and cerebral commissures. The data obtained demonstrate substantial restitution of somatosensory functions in animals after unilateral transection of the classical somatosensory pathways which were tested by neurological and behavioral methods. Cats with combined transection of the classical somatosensory pathways and telencephalic, diencephalic and mesencephalic commissures did not manifest any such rehabilitation. Exclusion of the direct visual control beyond the "deafferented" part of the body by optic tract transection is immaterial for these processes.
