In result study of structural organization of neural receptive fields (RFs) and their different zones on the prestriate cortex level was shown that neural RFs in this area have hypercomplex structure and consist of some spatial different excitatory zones. Orientation and velocity selectivity and spatial-frequency characteristics of the excitatory zones of(More)
As a result studying the features of single neurons of prestrial cortex (field 21) of a cat the interhemispheric differences are revealed. It is found that the sizes of receptive fields (RF) of the neurons of this region in the left hemisphere is 1.5 larger as in the right one. The RFs of the left hemisphere consist of zones (mainly 5-9) than the RFs of the(More)

Spatial-frequency characteristics of receptive field (RF) neurons were studied in the cat area 21. The characteristics differed in different parts of the RFs. The data obtained reveal that the spatial-frequency tuning of RFs as a whole is the result of spatial interaction (algebraic summation) of different tunings of RF's different parts.
The interrelationship between the size of receptive fields and the eccentricity in areas 21, 19 and 7 of both hemispheres was studied on immobilized cats. Correlation between the receptive fields size and the eccentricity in area 21 in the both hemispheres was low (R = 0.15; P greater than 0.05). In areas 19 and 7 the correlation of the size fields and(More)
In given work results of researches functional organization of neural networks at associative cortex level in intact and after total corpus callosum section (Cc sec) of cat's brain. In result of the given researches is established, that after total Cc sec the brain is exposed significant morphological and functional changes. Is shown, that Cc sec is(More)
The influence of GABA injection (intraperiotoneal) on the sensitivity to sound and behaviour was studied on KM line rats, in which a strong sound produces epileptiform seizures, and on sound-resistant Wistar line rats. It was shown that in the KM line rats the previously elaborated motor alimentary conditioned reflex was impaired for several hours after the(More)
