【摘要】：語言中的序列加工是將一系列語音單元加工成單詞或句子,序列加工在語言感知和言語產(chǎn)生中扮演著非常重要的角色,然而言語產(chǎn)生過程本身就十分復(fù)雜,其內(nèi)在的序列加工神經(jīng)機(jī)制還尚不清楚,在本文中我們觀察了序列感知,序列執(zhí)行,序列規(guī)劃和估計(jì)(想象),感覺-想象整合序列加工機(jī)制的神經(jīng)機(jī)制,并提出三個(gè)問題:(1)序列加工機(jī)制能否導(dǎo)致偏側(cè)化;對于不同內(nèi)容的加工,如音節(jié)序列,音高序列和手指按鍵任務(wù)序列加工機(jī)制的偏側(cè)是怎樣的。(2)不同的言語產(chǎn)生過程(序列感知,序列執(zhí)行,序列規(guī)劃和估計(jì))是如何影響偏側(cè)性的。(3)感覺-想象整合的序列加工機(jī)制過程的神經(jīng)表征及偏側(cè)是怎樣的。本研究中,采用了 fMRI技術(shù)觀察音節(jié),音高,手指按鍵任務(wù)中序列加工的神經(jīng)機(jī)制,并采取特殊的fMRI偏側(cè)化分析方法進(jìn)行左右腦對比。我們的結(jié)果顯示:(1)音節(jié)序列感知過程是無偏側(cè)的,而序列規(guī)劃和估計(jì)過程是左偏側(cè)的。(2)語音序列的感覺-想像過程的是無偏側(cè)的,且音節(jié)序列位于左側(cè)顳葉偏側(cè)不顯著,音高序列位于兩側(cè)的顳葉。(3)音高任務(wù)的動作執(zhí)行階段,序列加工機(jī)制位于額中回,顳頂聯(lián)合區(qū);在手指按鍵任務(wù)中序列加工機(jī)制位于額上回,而音節(jié)的序列加工機(jī)制在序列規(guī)劃和估計(jì)時(shí)位于頂葉。序列加工機(jī)制因加工階段不同,內(nèi)容不同而有不同的偏側(cè)和神經(jīng)表征。
[Abstract]:Sequence processing in language is to process a series of speech units into words or sentences. Sequence processing plays a very important role in language perception and speech production. However, the process of speech production is very complex.Three questions are raised: can the processing mechanism of the sequence lead to lateralization; for different content processing, such as syllable sequence,Different speech production processes (sequence awareness, sequence execution, sequence awareness, sequence execution) are different in pitch sequence and finger keystroke task sequence processing mechanism.Sequence planning and estimation) how to affect the laterality of the neural representation of the process of sensory-visual integration of sequence processing and what is the laterality of the process.The sequence processing mechanism is located in the middle frontal gyrus, the temporoparietal joint region, and the sequence processing mechanism in the superior frontal gyrus in the finger keystroke task.The sequence processing mechanism of syllable is in the parietal lobe in sequence planning and estimation.The mechanism of sequence processing has different side and nerve characteristics because of different processing stage and content.
