Brain mapping with a cognitive ontology.
Our approach characterizes the task conditions that correspond to each brain image with terms from a cognitive ontology. Forward inference maps differences between brain responses for a given term and its neighbors in the ontology, i.e. closely related psychological notions. Reverse inference is achieved by predicting the terms associated with the task from brain activity. The figure depicts the analysis of visual object perception tasks with motor response. A forward inference captures brain responses in motor, primary visual and high-level visual areas. Reverse inference captures which regions or neural substrate are predictive of different terms, discarding common response to different tasks, here in the primary visual cortex.
