摘要: The learning of perceptual skills is thought to rely upon multiple regions in the cerebral cortex, but imaging studies have not yet provided evidence about changes neural activity that accompany visual skill learning. Functional magnetic resonance (fMRI) was used examine activation posterior brain associated with acquisition mirror-reading for novel and practiced stimuli. Multiple occipital lobe, inferior temporal superior parietal cortex cerebellum were involved reading mirror-reversed compared normally oriented text. For stimuli, skilled decreased right increased left lobe. These results suggest read text involves a progression from visuospatial transformation direct recognition transformed letters. Reading practiced, relative unpracticed, stimuli cortices, occipito-parietal lateral regions. By examining item-specific repetition priming same task, this study demonstrates both these forms exhibit shifts set structures contribute performance.
