| Abstract | Japanese quails have a variety of calling patterns depending on sex and age. Sexually mature adult males emit a characteristic crow which has a frequency-modulated acoustical trill element. Recently we reported that the intercollicular nucleus of the mesencephalon is the vocal neural system for producing the distress call in untreated chick and the crowing vocalization in testosterone-treated chick in Japanese quails. We postulated that the intercollicular nucleus could mediate this testosterone action on vocal behavior. The present study showed histologically that the intercollicular nucleus neurons of adult males have many more dendrites than those of females. The adult males produced the call with trill element with electrical stimulation of the intercollicular nucleus alone. Females produced the simple call, which has no frequency modulation, with electrical stimulation; 4 days after the testosterone treatment together with electrical stimulation, they also produced the call with trill element, the characteristic call of males. We suggest that the vocal neural system in the intercollicular nucleus is modulated by testosterone during development and produces the crow in males, and the intercollicular nucleus neurons in adults mediate the action of testosterone on vocal behavior. The crow of adult males could therefore be due to effects of testosterone on the neural mechanism in the intercollicular nucleus. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
