Electrophoretic patterns of insoluble proteins in the sensory cerebral cortex of visually deprived and normal kittens.
نویسندگان
چکیده
Insoluble proteins were investigated in the visual cortex (area 17) and somatic sensory cortex of one month old kittens. Visual deprivation did not affect the electrophoretic pattern but changed percentage distribution of proteins in both cortices. Some of the alterations seemed to appear only in the visual cortex, which is morphologically and functionally deficient in deprived kittens. Electrophoretic patterns of normal kittens differed from those of normal adult cats.

THEIMPORTANCEOFNORMALSENSORYSTIMULATION inthedevelopment and maintenance of the nervous system is now generally recognized. In the visual system this problem has usually been approached by examining the effects of sensory deprivation on structure and behavior (see reviews by Hebb (12) and Riesen (28)). An obvious way of extending this work would be to examine electrophysiologically the function...

متن کاملThe effect of first visual stimulation on incorporation of labelled leucine into cerebral cortex of binocularly deprived kittens.
One-month old kittens, binocularly deprived with hoods from birth, were used. Before the experiments in which visual stimulation was applied the brainstem of kittens was transected at the pretrigeminal level. Cortical EEG activity and ocular behavior indicated that the isolated cerebrum of preparations was usually awake during experiment. Patterned visual stimulation was directed to one hemisph...
متن کاملPrevalence of Angle’s malocclusion in sensory-deprived and normal school children of age group of 12-16 years in India: A study conducted in 2016-2018
BACKGROUND AND AIM: Malocclusion has multifactorial etiology and the environmental factors play a major role in the occurrence of a malocclusion. Physical constraint faced by the disabled children may increase the chance of having malocclusion more than their normal counterparts. Thus, this study was done to evaluate the difference in the prevalence of Angle’s ...
متن کاملEffect of sensory disuse on geniculate afferents to cat visual cortex.
In the kitten, as little as a week of monocular lid suture during early life causes a remarkable remodeling of the geniculocortical projections serving the deprived eye (Antonini & Stryker, 1993a, 1996). While the physiological effects of monocular deprivation have been shown to be due to competitive interactions between the projections serving the two eyes, it is not known whether these morpho...
