“…The refinement of RF size differs in several ways from maturation of other RF properties (for review see Daw 2006). The initial formation of ocular dominance columns in V1 occurs prenatally (Rakic 1976;Horton and Hocking 1996;Hevner 2000), despite binocular lid suture (Sherk and Stryker 1976;Crair et al 1998), dark rearing (Mower, Berry, et al 1981;Stryker and Harris 1986), or enucleation (Crowley and Katz 1999).…”

Visual deprivation is reported to prevent or delay the development of mature receptive field (RF) properties in primary visual cortex (V1) in several species. In contrast, visual deprivation neither prevents nor delays refinement of RF size in the superior colliculus (SC) of Syrian hamsters, although vision is required for RF maintenance in the SC. Here, we report that, contrary to expectation, visual cortical RF refinement occurs normally in dark-reared animals. As in the SC, a brief period of visual experience is required to maintain V1 RF refinement in adulthood. Whereas in the SC, 3 days of visual experience within a sensitive period (P37-40) was sufficient to protect RFs from deprivation-induced enlargement in adulthood, 7 days (P33-40) were required for RF size maintenance in V1. Thus, spontaneous activity is sufficient for RF refinement at these 2 levels of the visual pathway, and visual input is necessary only to prevent deprivation-induced RF enlargement in adulthood. These studies show that sensory experience during a late juvenile sensitive period protects the visual pathway against sensory deprivation in adulthood, and suggest that more importance may have been placed on the role of early visual experience in visual RF development than is warranted.

“…Moreover, the maturation of neuronal response properties in the visual cortex is dependent on the maturation of cells at lower levels of the visual system (Boothe et al, 1988;Daw, 2005). The maturation of RF tuning properties during development underlies the improvement in visual performance by higher order mammals like humans and monkeys (Tanaka and Fujita, 2000;Daw, 2005). Previous findings have shown that the maturity of RF properties of neurons can partially account for the improvement of behavioral performance in macaques .…”

This review aims to discuss (1) the refinement of mammalian visual cortical circuits and the maturation of visual functions they subserve in primary visual cortex (V1) and other visual cortical areas, and (2) existing evidence supporting the notion of differential rates of maturation of visual functions in different species. It is well known that different visual functions and their underlying circuitry mature and attain adultlike characteristics at different stages in postnatal development with varying growth rates. The developmental timecourse and duration of refinement varies significantly both in V1 of various species and among different visual cortical areas; while basic visual functions like spatial acuity mature earlier requiring less time, higher form perception such as contour integration is more complex and requires longer postnatal time to refine. This review will highlight the importance of systematic comparative analysis of the differential rates of refinement of visual circuitry and function as that may help reveal underlying key mechanisms necessary for healthy visual development during infancy and adulthood. This type of approach will help future studies to establish direct links between various developmental aspects of different visual cortical areas in both human and animal models; thus enhancing our understanding of vision related neurological disorders and their potential therapeutic remedies.
