摘要:	摘要： Practice-dependent changes in brain structure can occur in task relevant brain regions as a result of extensive training in complex motor tasks and long-term cognitive training but little is known about the impact of visual perceptual learning on brain structure. Here we studied the effect of five days of visual perceptual learning in a motion–color conjunction search task using anatomical MRI. We found rapid changes in gray matter volume in the right posterior superior temporal sulcus, an area sensitive to coherently moving stimuli, that predicted the degree to which an individual's performance improved with training. Furthermore, behavioral improvements were also predicted by volumetric changes in an extended white matter region underlying the visual cortex. These findings point towards quick and efficient plastic neural mechanisms that enable the visual brain to deal effectively with changing environmental demands. •VPL induced changes in cortical volume in pSTS that predicted behavioral improvements.•White matter changes underlying the early visual cortex correlated with behavior.•Structural changes were found after five days of VPL in a motion–color search task. 其他題名： Neuroimage 出版者： Amsterdam: Elsevier Inc 出版日期： 2013-11-01 出處： NeuroImage, 2013-11, Vol.81, p.205-212 版權： 2013 Elsevier Inc. 版權： 2014 INIST-CNRS 版權： Copyright © 2013 Elsevier Inc.
