Abstract

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.
