NIF Literature is accessed through the NIF search interface as one of the core resources of NIF. Literature results are displayed under the Literature tab, with simultaneous search across multiple literature indices, including Pub Med, Open Access and neuroscience-centered literature databases. Neuroscience centered indices include the Neuronal Morphology database, containing a curated set of articles relating to neuronal morphology assembled by the NeuroMorpho resource. We also maintain a neuroscience literature corpus, assembled via full text indexing of content from neuroscience journals from 1995-2008. This index is no longer actively maintained but will be available for the immediate future.
Searches through the NIF interface take advantage of the NIF vocabularies to expand or refine searches based on synonyms and related concepts, e.g., super classes, sub classes or parts. Open Access and Neuroscience literature provide full text access. All results utilize the NIF entity recognition tools, highlighting terms and phrases that are contained within the NIF vocabularies. These entities may be further explored through a right click to access NIF cards; little applications that provide more information.
Full text results may also be further explored using the NIF Textpresso for Neuroscience interface, which provides the user additional category (e.g. brain region) and filter options for refining a search across the open access and Neuroscience literature centered databases. One of the most powerful features is the ability to include in a search “buckets” of search terms from the NIF Vocabularies. For example, it is possible to launch a search within Textpresso for “PKC.” After Textpresso returns results for this search, you may refine your search by choosing a category (e.g. brain region). Textpresso results will then highlight your keyword as well as more than 500 brain regions and subregions. Similar searches can be performed for genes, drugs, cell types, diseases and techniques.
