We have previously reported anatomical and chemical changes in the cerebral cortex of rats living in an enriched, stimulating environment. The present study includes additional histological measures such as more extensive depth measures, differential cell counts, and cell size measurements. 
Extensive cortical depth measurements and neuron size increases in the cortex of environmentally enriched rats
This study is another in a series of investigations attempting to define the changes in the brain as a consequence of environmental manipulation. Cortical depth and neuron size measurements were
Morphological Measurements in the Aging Rat Cerebral Cortex
TLDR
The present chapter includes some of the same data, but adds new information from the somatosensory cortex which has more recently been obtained, to compare with previous work.
Cortical depth changes in enriched and isolated mice.
TLDR
The occipital cortical depth was determined in laboratory mice at both 14 and 20 days of age and after various periods of postweaning exposure to enrichment or isolation and may reflect the extent of cortical neuronal development and associated metabolic activity.
Environmental enrichment and the brain.
Microtubular proteins in the occipital cortex of rats housed in enriched and in impoverished environments
TLDR
In occipital cortices of rats housed in an impoverished environment: increased cortical depth, increased cholinesterase, an increased number of glia cells, enlargement of neuronal cell bodies, more dendritic branching, and fewer but larger synapses.
Cellular composition of a cerebral hemisphere primary culture
TLDR
The enrichment in astroglial-like cells makes the cultures a satisfactory astrocytic glial-cell model, at least for some purposes, and available markers and methods for characterizing cell elements in a culture system are focused on.
Influence of Enriched Environment on Spatial Learning following Cerebral Insult
TLDR
The role of an enriched environment on brain plasticity following experimentally-induced lesions is discussed and rats that are housed in an enrichment environment can better compensate for brain lesion-induced deficits and resist neurodegeneration.
Enriched environment increases the total number of CNPase positive cells in the corpus callosum of middle-aged rats.
TLDR
The present study provided the first evidence of environmental enrichment-induced increases in the total number of CNPase positive cells in the corpus callosum of middle-aged rats.
Regional effects of wheel running and environmental enrichment on cell genesis and microglia proliferation in the adult murine neocortex.
TLDR
It is reported that voluntary wheel running led to a regional increase in the number of newly generated cortical microglia, adding a new aspect to the question of microglial function in the healthy brain and of how adult brain cells can plastically react to physiological stimuli.

Autoradiographic Examination of the Effects of Enriched Environment on the Rate of Glial Multiplication in the Adult Rat Brain
TLDR
Autoradiographic Examination of the Effects of Enriched Environment on the Rate of Glial Multiplication in the Adult Rat Brain finds that enrichment in the environment affects the rate of expansion in the rat brain.
Chemical and Anatomical Plasticity of Brain Changes in brain through experience, demanded by learning theories, are found in experiments with rats
TLDR
Rearing complexity affects branching of dendrites in the visual cortex of the rat and the effects of environmental complexity and training on brain chemistry and anatomy are studied.
A Nissl Method Using Buffered Solutions of Thionin
TLDR
A satisfactory procedure using thionin in dilute buffered solutions was developed and a rapid method for staining the chromophilic substance of formalin-fixed nerve cells differentially without resorting to over-staining and subsequent acid-decolorizing was developed.
