Research on humans suggests that lack of stimulation delays and impairs cognitive development. Research also finds that attaining and engaging in higher levels of education, environments in which people participate in more importance of environmental studies pdf cognitively stimulating activities, results in greater cognitive reserve. 1947 found that rats raised as pets performed better on problem solving tests than rats raised in cages. His research, however, did not investigate the brain nor use standardized impoverished and enriched environments.
However, the increase in synapse numbers has been observed generally to reduce with maturation. Synapses in animals in enriched environments show evidence of increased synapse activation. Synapses tend to also be much larger. This increased energy consumption is reflected in glial and local capillary vasculation that provides synapses with extra energy. The volume of glial cell nuclei for each synapse is higher by 37. 35 μm compared to 4.
6 μm compared to 34. However, its relevance has been questioned for the behavioral effects of enriched environments. Research in animals suggests that environmental enrichment aids in recovery from an array of neurological disorders and cognitive impairments. Although most of these experiments used animal subjects, mainly rodents, researchers have pointed to the affected areas of animal brains to which human brains are most similar and used their findings as evidence to show that humans would have comparable reactions to enriched environments. The tests done on animals are thus meant to represent human simulations for the following list of conditions. The study found that autistic children who receive olfactory and tactile stimulation along with exercises that stimulated other paried sensory modalities clinically improved by 42 percent while autistic children not receiving this treatment clinically improved by just 7 percent. The same study also showed that there was significant clinical improvement in autistic children exposed to enriched sensorimotor environments, and a vast majority of parents reported that their child’s quality of life was much better with the treatment.
