Neuroscience Information Framework provides a web-based search portal of neuroscience resources and tools including images, genes, clinical trials, datasets, multimedia, models, software, etc contained on databases that are not accessed through a typical search engine (hidden or invisible web). This is a great starting point for searching neuroscience-related data.
A video tutorial can be found here.
Connectome Workbench is a "visualization and discovery tool used to map data generated by the Human Connectome Project. This tool allows you to explore multiple types of data, including connectivity data, in a fully interactive way".
The National Database for Autism Research supports data sharing across a broad array of clinical, genomic, and brain imaging autism research data.
The Autism Chromosome Rearrangement Database is a collection of hand curated breakpoints and other genomic features, related to autism, taken from publicly available literature: databases and unpublished data
Gemma "is a web site, database and a set of tools for the meta-analysis, re-use and sharing of genomics data, currently primarily targeted at the analysis of gene expression profile"
Neurocarta "is a one-stop shop for researchers looking for candidate genes for any disorder of interest. In Neurocarta, they can review the evidence linking genes to phenotypes"
Allen Brain Atlas data portal from the Allen Institute for Brain Science contains a collection of public resources including gene expression, neuroanatomical data etc from human, mouse, and primate.These data can be analyzed and viewed using the portal tools (e.g. 3D viewer) as well as downloaded.
The Human Connectome Project collects vdata using advanced brain imaging methods on a large population of healthy adults, and makes the data freely available.
