Visual form discrimination from luminance or disparity cues: functional anatomy by PET.
With the purpose of elucidating the functional fields involved in the discrimination of visual form based either on luminance or binocular disparity cues, we used PET to measure changes in regional cerebral blood flow (rCBF) in ten volunteers while they performed visual discrimination tasks. The averaged standardized subtraction images (delta rCBF) were analysed for statistically significant changes between the form tasks and their reference tasks. Twenty cortical fields in the visual associa...Expand abstract
