Neural networks: neural systems I.
The writers present the findings of a structural equation mapping analysis of a positron emission tomography regional study of cerebral blood flow, in which participants performed a visual perceptual matching task concerning either object identification or spatial location. They argue that the inhi...

Randal su: Brain function localization Form perception Space perception sug: subj: Brain function localization Form perception Space perception ab: The writers present the findings of a structural equation mapping analysis of a positron emission tomography regional study of cerebral blood flow, in which participants performed a visual perceptual matching task concerning either object identification or spatial location. They argue that the inhibitory correlation influences on the frontal cortex during the object identification task came from the dorsal pathway and that they came from the ventral pathway during the spatial location task. In addition, they contend that the same visual signal is selectively passed on to the appropriate pathway on the basis of the specific requirements of the task. Furthermore, they assert that the brain regions that form the pathways from the visual association cortex to the frontal cortex are thought to provide specialized processing of the signal to facilitate performance of the specified task. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
