SUMMARYThe effect of visual deprivation on synaptic contacts in the visual cortex was studied with the electron microscope. The deprivation was achieved by unilateral lid suture in 14-day old white rats before eye opening after which the animals were kept for 8 weeks. The density and the size of synaptic contacts in the upper part of the visual cortex (from the surface of layer I1 up to V) were estimated. The mean density of synapses of the visual cortex supplied by the deprived eye was 20% less than on the control side, the upper levels of the cortex being more affected. The mean size of synaptic contacts was larger (+7.5%) in the upper levels of the deprived cortex. No right left difference in density and size were found in control animals.

“…HAmori (1966) showed a considerable rearrangement of persisting elements and newly formed synaptic contacts in similar chronic preparations. Cragg (1967Cragg ( , 1968 compared the density and size of axon terminals in rats and monkeys reared in darkness with those of normal controls. 285…”

“…Over the last 10–15 years, we have gained considerable knowledge regarding the epidemiology of work‐related nail gun injuries. As the tools appeared in the marketplace in the 1960s, injury case reports began to appear in the medical literature; they continue and have expanded to include a number of case series [Cragg, ; Richardson, ; Wu et al, ; le Nobel and Wing, ; Queensland Injury Surveillance Unit, ; Kizer et al, ; Lee and Sternberg, ; Alberico et al, ; Hoffman et al, ; Bruno et al, ; Beaver and Cheatham, , Jithoo et al, ; Takagi et al, ; Horne and Corley, ; Ling et al, ; Rhee et al, ]. Passive and active surveillance efforts followed [Queensland Injury Surveillance Unit, ; Baggs et al, , ; Dement et al, ; Lipscomb et al, ,, ; Lipscomb and Jackson MMWR, ] as did descriptive and analytic epidemiologic studies [Lipscomb et al, , , , 2010a, 2010b].…”
