Brief Daily Periods of Binocular Vision Prevent Deprivation-Induced Acuity Loss
The role of experience in the development of the central visual pathways has been explored in the past through examination of the consequences of imposed periods of continuously abnormal or biased visual input. The massive changes in the visual cortex (area 17) induced by selected early visual experience, especially monocular deprivation (MD) or experience (ME) where patterned visual input is p...
متن کاملShort periods of concordant binocular vision prevent the development of deprivation amblyopia.
Based in part on deprivation studies, it is generally agreed that the development of vision and of the central visual pathways of higher mammals such as cats and primates is experience-dependent. Past deprivation experiments employed periods of exclusively abnormal early visual input. Because of the absence of any normal visual input, such studies indicate only the extremes to which the visual ...
متن کاملCortical effects of brief daily periods of unrestricted vision during early monocular form deprivation.
Experiencing daily brief periods of unrestricted vision during early monocular form deprivation prevents or reduces the degree of resulting amblyopia. To gain insight into the neural basis for these "protective" effects, we analyzed the monocular and binocular response properties of individual neurons in the primary visual cortex (V1) of macaque monkeys that received intermittent unrestricted v...
متن کاملBrief daily binocular vision prevents monocular deprivation effects in visual cortex.
Even short periods of early monocular deprivation result in reduced cortical representation and visual acuity of the deprived eye. However, we have shown recently that the dramatic deprivation effects on vision can be prevented entirely if the animal receives a brief period of concordant binocular vision each day. We examine here the extent to which the cortical deprivation effects can be count...
متن کاملBrief daily periods of unrestricted vision preserve stereopsis in strabismus.
PURPOSE This study examines whether brief periods of binocular vision could preserve stereopsis in monkeys reared with optical strabismus. METHODS Starting at 4 weeks of age, six infant monkeys were reared with a total of 30 prism diopters base-in split between the eyes. Two of the six monkeys wore prisms continuously, one for 4 weeks and one for 6 weeks. Four of the six monkeys wore prisms b...
