Development and study of large-scale computational models of the human brain, and their use to simulate cognitive functions, is becoming increasingly feasible. However, construction of integrated models that span multiple cognitive systems (language, memory, reasoning, learning, sensorimotor control, executive functions, etc.) is currently inhibited by the absence of any systematic catalog of experimentally documented associations between specific behavioral functions and specific brain regions. In this report we provide a prototype for such a mapping in the form of a semantic network. While preliminary and not comprehensive, the results presented here support the idea that an online mapping between cognitive function and cortical/subcortical structures can be developed as a useful reference source.
