1. A method of interpreting cognitive response comprising: collecting baseline neural activity data that maps a neural activation absent a stimulus onto neuronal structure of a subject brain of a plurality of subjects absent said stimulus; exposing each of said plurality of subjects to said stimulus; collecting stimulated neural activity data that maps a neural activation during said stimulus onto said neuronal structure of the subject brain from each of said plurality of subjects while each of said plurality of subjects is exposed to said stimulus; plotting a unique three-dimensional cognitive engram representative of a common stimulated neural activity caused by said stimulus from said plurality of subjects to a level of voxels; and compiling said cognitive engram in a database containing a plurality of engrams, each of said plurality of engrams associated with a different stimulus for interpreting cognitive response.
