Mapping the functional neuroanatomy of the intact human brain with brain work imaging

Haxby, James V., Grady, Cheryl L., Ungerleider, Leslie G., Horwitz, Barry·1991·Neuropsychologia

Abstract

The recent development of noninvasive methods for measuring local rates of energy metabolism or blood flow in the brain has made it possible to investigate functional neuroanatomy in healthy human subjects. The best of these methods, high resolution measurement of regional cerebral blood flow (rCBF) with positron emission tomography (PET), provides a precision of anatomical localization that far exceeds that attainable with human brain lesion studies. Moreover, the study of healthy subjects avoids possible confounding effects of brain lesions, such as compensatory reorganization of brain function. PET-rCBF studies have already identified several cortical areas involved in higher-order visual processing, indicating that functional neuroimaging may yield a map of human visual cortex analogous to maps that have been developed by vision research in nonhuman primates. PET-rCBF studies of imagery and language demonstrate the potential of functional neuroimaging to map regions of human cortex that perform functions that cannot be studied so easily in nonhuman primates or perform functions that humans do not share with other species.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
