摘要

听觉言语工作记忆（AVWM）是一个重要的认知过程，它允许个体存储和操作听觉信息。本研究探讨了经颅直流电刺激（tDCS）对无义听觉音节AVWM表现的影响，并考察了不同刺激蒙太奇的作用。30名健康参与者接受了三种刺激蒙太奇的tDCS：阳极-左听觉皮层/阴极-左背外侧前额叶皮层（DLPFC）、阳极-左听觉皮层/阴极-右脸颊和假刺激。结果表明，左侧听觉皮层的阳极tDCS同时在左侧DLPFC上进行阴极刺激，可以改善1-back任务的表现；而左侧听觉皮层的阳极tDCS在右侧脸颊上进行阴极刺激，可以改善1-back和2-back任务的表现。这些发现表明，左听觉皮层在AVWM中起着关键作用，并强调了在tDCS研究中考虑刺激蒙太奇的重要性。

tDCS over the left auditory cortex enhances working memory of nonsense auditory syllables: The role of stimulation montages

Auditory verbal working memory (AVWM) is a crucial cognitive process that allows individuals to store and manipulate auditory information. This study investigates the effects of transcranial direct current stimulation (tDCS) on AVWM performance using nonsense auditory syllables and examines the role of different stimulation montages. Thirty healthy participants received tDCS with three stimulation montages: anode-left auditory cortex/cathode-left dorsolateral prefrontal cortex (DLPFC), anode-left auditory cortex/cathode-right cheek, and sham stimulation. Results showed that anodal tDCS over the left auditory cortex with concurrent cathodal stimulation over the left DLPFC improved 1-back task performance, while anodal tDCS over the left auditory cortex with cathodal stimulation over the right cheek improved both 1-back and 2-back task performance. These findings suggest that the left auditory cortex plays a critical role in AVWM and highlight the importance of considering stimulation montage in tDCS studies.

期刊介绍： The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
