Abstract

There is preliminary evidence that high-frequency repetitive transcranial magnetic stimulation targeting the right dorsolateral prefrontal cortex (DLPFC) could reduce cue-induced sexual arousal. Here, we aimed to replicate this finding by using transcranial direct current stimulation (tDCS). In a randomized, double-blind, sham-controlled crossover study design, 24 healthy male participants received anodal tDCS over right DLPFC, anodal tDCS over left DLPFC, and sham tDCS with exposure to neutral and sexual video cues before and after each intervention. None of the interventions significantly reduced subjective sexual arousal. Stimulation parameters should be varied in further studies to identify factors relevant to the intended effect.

前额叶经颅直流电刺激对性唤起的影响：概念验证研究

有初步证据表明，针对右背外侧前额叶皮层（DLPFC）的高频重复经颅磁刺激可以减少线索诱导的性唤起。在这里，我们的目的是通过使用经颅直流电刺激（tDCS）来复制这一发现。在一项随机、双盲、假对照的交叉研究设计中，24名健康男性参与者在每次干预前后接受阳极tDCS而非右侧DLPFC、阳极tDCS或左侧DLPFC，以及暴露于中性和性视频线索的假tDCS。这些干预措施都没有显著降低主观性唤起。应在进一步研究中改变刺激参数，以确定与预期效果相关的因素。

期刊介绍： Neurophysiologie Clinique / Clinical Neurophysiology (NCCN) is the official organ of the French Society of Clinical Neurophysiology (SNCLF). This journal is published 6 times a year, and is aimed at an international readership, with articles written in English. These can take the form of original research papers, comprehensive review articles, viewpoints, short communications, technical notes, editorials or letters to the Editor. The theme is the neurophysiological investigation of central or peripheral nervous system or muscle in healthy humans or patients. The journal focuses on key areas of clinical neurophysiology: electro- or magneto-encephalography, evoked potentials of all modalities, electroneuromyography, sleep, pain, posture, balance, motor control, autonomic nervous system, cognition, invasive and non-invasive neuromodulation, signal processing, bio-engineering, functional imaging.
