采用SPECT和133xe对左颞叶病变的深部语言障碍患者进行脑激活研究。激活范式包括被动听外语为基准、音素监测条件和语义词监测条件。在语义条件下观察到的右中颞叶皮层的特异性激活与右半球在具体词汇加工中的代偿作用的假设是一致的。这个病例说明了功能成像对更好地理解脑损伤后功能恢复的神经机制的兴趣。
A brain activation study using SPECT and133Xe in a deep dysphasic patient with left temporal lesion is presented. The activation paradigm consisted of a passive listening to foreign language as baseline, a phoneme monitoring condition and a semantic word monitoring condition. The specific activation of the right middle temporal cortex observed in the semantic condition is congruent with the hypothesis of a compensatory role of the right hemisphere in processing concrete words. This case illustrates the interest of functional imaging for a better understanding of neural mechanisms of functional recovery after brain injury.
