Higher-order dendritic branching is considerably greater in Golgistained neurons from the occipital cortex of rats reared in groups in a complex environment than in similar neurons of littermates reared individually in laboratory cages have intermediate amounts of branching, while lower-order branching did not appear to be affected by any rearing environment. 
Cerebellar plasticity: modification of Purkinje cell structure by differential rearing in monkeys.
The data indicate that the social and physical environment during development influences the morphology of cerebellar Purkinje cells.

Dendritic maturation of pyramidal neurons in layers III and V of the rat visual cortex was quantified in rapid Golgi‐stained tissue from socially housed hooded rats at ages 15, 30, and 60 days. A
Effect of the richness of the environment on the cat visual cortex
The Nv of both types of synapses were estimated in two groups of six cats, paired by litter and by sex, and raised either in isolation or in a colony from the time of weaning to the age of 8 months.


Early Experience Effects upon Cortical Dendrites: A Proposed Model for Development
The effects of environmental stimulation on the development of rat cortical pyramidal cell synaptic loci (dendritic spines) and the number of such cells staining by the rapid Golgi technique appear to be related to those that are functionally involved at the time of tissue preparation.
Quantitative synaptic changes with differential experience in rat brain.
Rats given experience in the enriched condition (EC) showed, in comparison to littermates in the impoverished condition (1C), synapses that averaged 52% greater in length but that were only 67% as numerous as in IC, so the EC size distribution could not have been derived simply by loss of small synapses from the IC distribution.
The effect of monocular deprivation on the synaptic contacts of the visual cortex.
The effect of visual deprivation on synaptic contacts in the visual cortex was studied with the electron microscope and the mean density of synapses supplied by the deprived eye was 20% less than on the control side, the upper levels of the cortex being more affected.
The Vertebrate Visual System
The 418 pages devoted to these and other structures portray the system as a whole in an orderly fashion and with considerable new material, including a detailed account of the blood supply and drainage.
A chlorate-formaldehyde modification of the Golgi method.
The method gives good results for microglia and oligodendroglia in addition to the usual staining of nerve cells and their processes.
