跨通道可塑性是指在缺少典型的主要感觉输入的情况下，感觉皮层的重组。了解这一现象有助于深入了解大脑功能及其改变和增强的潜力。利用功能磁共振成像，我们研究了早期耳聋如何影响成人大脑的跨模式可塑性和执行功能的组织。聋人(n=25；年龄：平均41.68，范围19~66，SD=14.38；女性16，男性9；听力：n=20；年龄：平均37.50，范围18~66，SD=16.85；女性15，男性5)被试执行四种视觉任务，分别涉及执行加工的不同成分：任务转换、工作记忆、计划和抑制。我们的研究结果表明，聋人在任务转换过程中会特异性地招募“听觉”区域。在聋人群体中，在任务转换过程中，顶端颞区的神经活动，尤其是右半球的神经活动，可以很好地预测行为表现，突出了观察到的皮质重组的功能相关性。我们的结果显示了典型感觉区域的执行过程，这表明大脑区域的发展和最终作用受到知觉环境经验的影响。利用功能磁共振成像，Manini，Vinogradova等人。表明聋人的听觉皮质参与了任务转换。这些发现表明，感觉皮质可以将其功能转变为更高层次的认知，而感觉体验塑造了大脑中的皮质重组和执行过程。
Crossmodal plasticity refers to the reorganization of sensory cortices in the absence of their typical main sensory input. Understanding this phenomenon provides insights into brain function and its potential for change and enhancement. Using functional MRI, we investigated how early deafness influences crossmodal plasticity and the organization of executive functions in the adult human brain. Deaf (n = 25; age: mean = 41.68, range = 19–66, SD = 14.38; 16 female, 9 male) and hearing (n = 20; age: mean = 37.50, range = 18–66, SD = 16.85; 15 female, 5 male) participants performed four visual tasks tapping into different components of executive processing: task switching, working memory, planning and inhibition. Our results show that deaf individuals specifically recruit ‘auditory’ regions during task switching. Neural activity in superior temporal regions, most significantly in the right hemisphere, are good predictors of behavioural performance during task switching in the group of deaf individuals, highlighting the functional relevance of the observed cortical reorganization. Our results show executive processing in typically sensory regions, suggesting that the development and ultimate role of brain regions are influenced by perceptual environmental experience. Using functional MRI, Manini, Vinogradova et al. show that the auditory cortex of deaf individuals is involved in task switching. These findings show that sensory cortices can change their function to higher-order cognition, and that sensory experience shapes cortical reorganization and executive processing in the brain.
