| Abstract | Selective attention to features of interest facilitates object processing in a cluttered and dynamic environment. Previous research found that distinct networks of regions across cortex are activated depending on the attended feature. These networks typically consist of posterior feature-preferring regions and anterior regions involved in attentional processes. In the current study, we investigated the role of white matter connections between the posterior and anterior regions within these networks for attention to features of novel colored dynamic objects. We asked participants to perform a 1-back feature-attention task while we acquired both functional and diffusion-weighted images. Using tract-based spatial statistics and probabilistic tractography, we found that the right superior longitudinal fasciculus (SLF) connected posterior and anterior object-processing regions and that voxels within the SLF correlated with response times on the task. Posterior and anterior regions that were anatomically connected also had increased functional connectivity relative to posterior and anterior regions that were not connected. Our results demonstrate that both functional and structural information has to be taken into account to understand selective attention and object perception. |

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.
