| Abstract | Effects of chronic overcrowding on the development of depressive-like behavior and changes in monoamine contents in the brain structures involved in the development of depression were studied in rats. It was shown that overcrowding increased grooming duration and did not change the number of crossed squares and postures in the open-field test. In the forced swimming test, overcrowding increased immobility time and deceased the duration of the first episode of active swimming, which attested to depressive-like behavior. Overcrowding reduced the content of dopamine in the striatum, its metabolites (homovanilic and dioxyphenylacetic acids) and dopamine metabolism rate in the hypothalamus, and increased the concentrations of norepinephrine, homovanilic acid, and dioxyphenylacetic acid in the olfactory bulb and homovanilic acid in the prefrontal cortex. No changes were found in the nucleus accumbens. Serotonin content did not change in all analyzed structures. It was hypothesized that the observed changes in the content of monoamines and their metabolites in certain brain structures could underlie the depressive-like behavior induced by overcrowding in rats. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
