Abstract

Over the past decade the use of informatics to solve complex neuroscientific problems has increased dramatically. Many of these research endeavors involve examining large amounts of imaging, behavioral, genetic, neurobiological and neuropsychiatric data. Superimposing, processing, visualizing and
interpreting such a complex cohort of datasets frequently becomes a challenge. We developed a new software environment that allows investigators to integrate multi-modal imaging data, hierarchical brain ontology systems, online genetic and phylogenic databases and 3D virtual data reconstruction models. The Laboratory of Neuro Imaging visualization environment (LONI Viz) consists of the following components: a sectional viewer for imaging data, an interactive 3D display for surface and volume
rendering of imaging data, a brain ontology viewer, and an external database query system. The synchronization of all components according to stereotaxic coordinates, region name, hierarchical ontology and genetic labels is achieved via a comprehensive BrainMapper functionality, which directly maps between position, structure name, database and functional connectivity information. This environment is freely available, portable and extensible and may prove very useful for neurobiologists, neurogenetisists, brain mappers and for other clinical, pedagogical and research endeavors.
