| Abstract | We examined the axonal transport of two strains of herpes simplex virus 1 (HSV-1) within the central nervous system of cebus monkeys. Each strain was injected into the "arm area" of the primary motor cortex. One strain, HSV-1(McIntyre-B), was transported transneuronally in the retrograde direction. It infected neurons at sites known to project to the arm area of the primary motor cortex (e.g., ventrolateral thalamus). In addition, "second-order" neurons were labeled in the deep cerebellar nuclei (dentate and interpositus) and in the globus pallidus (internal segment). This result supports the concept that the arm area of the primary motor cortex is a target of both cerebellar and basal ganglia output. In contrast, the other strain, HSV-1(H129), was transported transneuronally in the anterograde direction. It infected neurons at sites known to receive input from the arm area of the primary motor cortex (e.g., putamen, pontine nuclei). In addition, "third-order" neurons were labeled in the cerebellar cortex (granule and Golgi cells) and in the globus pallidus (largely the external segment). Our observations suggest that strain differences have an important impact on the direction of transneuronal transport of HSV-1. Furthermore, it should be possible to examine the organization of cerebellar and basal ganglia loops with cerebral cortex by exploiting transneuronal transport of HSV-1 and virus strain differences. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
