Michiru, one great resource to check out is the Brainmap database, which is accessible over the web and has the functionality you want. I take this description from their help file: "BrainMap relates brain locations to human behaviors and data sources. For any brain region, the behavioral conditions believed to support that behavior can be retrieved. BrainMap data naturally falls into a hierarchical structure. The highest level is the paper. Each paper is divided into one or more experiments. An experiment is a grouping, typically a pairing, of behavioral tasks for which differentially activated locations are reported. Behavioral conditions identify the particular effects for which each experiment was designed. Methodological details such as modality and tracer are also provided for each experiment. Each experiment includes one or more activated locations. Locations are the lowest, most basic level of the BrainMap hierarchy. All information within a paper is linked throughout the hierarchy, providing ease of access up and down the branches of the hierarchy." You could start at http://ric.uthscsa.edu/cgi-bin/brainmap.pl?help*000002*menu, which takes you to their help menu.
