1. A system for mapping behavior to brain regions of interest, the system comprising: one or more processors having associated memory with executable instructions encoded thereon such that when executed, the one or more processors perform operations of: selecting, using a functional-anatomical model coupled to a cognitive-behavior model, a set of high-definition neurostimulations, wherein the selected set of high-definition neurostimulations targets specific regions of a brain; sensing brain state data during application of the set of high-definition neurostimulations and performance of a selected behavioral task using at least one brain monitoring technique; assessing a set of behavioral performance deficiencies; associating the set of behavioral performance deficiencies with brain states in various brain regions; analyzing brain activity with a neuroimaging device as a plurality of behavioral tasks are performed, wherein the performance is used to parameterize the cognitive-behavior model; adapting the coupled functional-anatomical and cognitive-behavior models until desired brain state data are reached; and causing a device to deliver neurostimulation by applying an electrical current to the brain to induce the desired brain state data.
