Topographic mapping of cerebral blood flow and behavior.
This paper describes the methods for presenting (i) scores obtained by a subject in neuropsychologic tests as a map of the brain by assigning the various scores to those regions or areas of the brain where the specific function is supposed to be localized and (ii) similar maps of the regional cerebral blood flow measured by the extra-cranial detectors. The maps so produced can be displayed as top or side view topographic images. These imaging methods enable the user to comprehend large arrays of numbers in a readily interpretable manner, and will be useful in identifying the brain activity patterns associated with various neurological and psychiatric disorders. The methods described here also present an opportunity to integrate the behavioral information with anatomical and physiological data obtained using various neuro-imaging techniques.
