我们报告了一项大型研究 (n = 72)，使用经颅直流电刺激-脑电图 (tDCS-EEG) 相结合来研究以面部反转效应为索引的感知学习的调节。参与者参与了一项新旧识别任务，涉及混合的直立和倒立、正常和撒切尔式面孔。准确性结果显示，与假手术/对照相比，在 Fp3 头皮区域（放置在 Fp2 的阴极/参考电极）传递的阳极 tDCS 增加了正常面部的行为反转效应，并且这与 N170 事件相关电位分量的调制相关。与假手术/对照相比，正常面部的 N170 潜伏期和振幅的倒置效应降低，这扩展了最近在行为面部倒置效应降低的情况下结合 tDCS 和 EEG 的工作。我们的研究结果揭示了 N170 振幅和延迟之间的分离，以响应 tDCS 诱导的面部反转效应调制，从而促进了对负责感知学习的神经机制的理解。反转效应的行为调制跟踪 N170 振幅的调制，尽管它是负相关的（即，减少反转效应 - 较大的 N170 振幅反转效应，增加反转效应 - 减少 N170 振幅反转效应）。对于 N170 延迟，无论行为反转效应如何调节，我们使用的 tDCS 协议都会降低反转效应。
We report a large study (n = 72) using combined transcranial direct current stimulation-electroencephalography (tDCS-EEG) to investigate the modulation of perceptual learning indexed by the face inversion effect. Participants were engaged with an old/new recognition task involving intermixed upright and inverted, normal and Thatcherized faces. The accuracy results showed anodal tDCS delivered at the Fp3 scalp area (cathode/reference electrode placed at Fp2) increased the behavioural inversion effect for normal faces versus sham/control and this covaried with a modulation of the N170 event-related potential component. A reduced inversion effect for normal faces was found on the N170 latency and amplitude versus sham/control, extending recent work that combined tDCS and EEG in circumstances where the behavioural face inversion effect was reduced. Our results advance understanding of the neural mechanisms responsible for perceptual learning by revealing a dissociation between the N170 amplitude and latency in response to the tDCS-induced modulation of the face inversion effect. The behavioural modulation of the inversion effect tracks the modulation of the N170 amplitudes, albeit it is negatively correlated (i.e., reduced inversion effect—larger N170 amplitude inversion effect, increased inversion effect—reduced N170 amplitude inversion effect). For the N170 latencies, the inversion effect is reduced by the tDCS protocol we use irrespective of any modulation of the behavioural inversion effect.
