In the present study we investigated the effects of anodal transcranial direct current stimulation over the auditory cortex (AC) on the perception of rapidly changing acoustic cues. For this purpose, in 15 native German speakers the left or right AC was separately stimulated while participants performed a between-channel gap detection task. Results show that stimulation of the left but not right AC deteriorated the auditory perception of rapidly changing acoustic information. Our data indicate a left hemispheric dominance for the processing of rapid temporal cues in auditory non-speech sounds. Moreover, we demonstrate the ability of non-invasive brain stimulation to change human temporal information processing in the auditory domain.
在本研究中，我们调查了经颅直流电刺激听觉皮层（AC）对快速变化的声学线索感知的影响。为此，在 15 名母语为德语的人当中，分别刺激左或右 AC，同时参与者执行通道间间隙检测任务。结果表明，刺激左 AC 而非右 AC 会使快速变化的声学信息的听觉感知恶化。我们的数据表明，在处理听觉非言语声音的快速时间线索方面，左半球占主导地位。此外，我们证明了非侵入性脑刺激能够改变听觉域中人类的时间信息处理能力。
