| 摘 要： | 本文采用近红外光学漫射成象技术成功观测了左右前额区在知觉与语义编码中的活动。 发现大脑在完成上述两任务时,左前额的活动显着地强于右前额,语义加工引起的活动显着地强于知觉加工。 对于每一侧而言,与浅加工相比,深加工时的活动主要集中在下前额叶。上述结果进一步证实了左前额叶在语义加工中的作用。 |
| 关 键 词： | 近红外光谱 前额叶 语义加工 |

| Abstract: | It is explored the possibility to measure the functional activation of prefrontal region during semantic encoding with near infrared diffusive imaging.Comparing the results of the two groups,significant activations were observed in left prefrontal cortex relative to right prefrontal cortex,during semantic encoding task than during non semantic encoding task.In each task the activation focus mainly located in the inferior part of the prefrontal region.This provides additional support for the function of the left inferior prefrontal lobe ion semantic processing. |
| Keywords: | Near infrared spectroscopy Prefrontal lobe Semantic processing |
