项目摘要

A previous study (Grunwald et al 2014a) has shown significant changes in the brain electrical activityof theta and beta power immediately before and after spontaneous facial self-touch gestures (sFSTG).The change dynamics of the EEG parameters across the entire experiment suggested thatspontaneously performed self-touch of the facial skin may modulate working memory processes andsimultaneously occurring emotional processes. If, in contrast, the examiner instructed the participantsto touch their face, no such pre-post EEG changes occurred. These finding are the firstneurobiological evidence in support of the hypothesis that movements directed to the own body mayfulfil regulatory functions. Respective research topics may provide promising insights in humanbehavior on the level of neurobiological foundational research as well as in clinical settings.The goals of the study under application are the following: a) elucidation of the brain electrical patterns of activation during the spontaneous facial self-touch, b) analysis of the duration and location of the sFSTG in relation to the brain electrical activity patterns before, during and after the sFSTG, c)analysis of the sFSTG characteristics (left vs. right hand; ipsilateral vs. contralateral face regions) inrelation to the brain electrical activity patterns before, during and after the sFSTG, d) elucidation of the gender specific characteristics of sFSTG concerning goals (a) through (c), and e) elucidation ofbehavioural effects and brain electrical changes caused by preventing the participant from performingsFSTG.Altogether, 56 men and 56 women between 20 and 35 years of age will be tested with the studydesign of Grunwald (2014a). Spectral and Wavelet analyses will be conducted of the conventionalband widths recorded with a 19 channel EEG. Movement and skin contact dynamics of the sFSTG will be registered by existing microprocessor acceleration sensors. The total duration of the study,including implementation, data analysis and manuscript submission will be 12 months.

先前的一项研究（Grunwald et al 2014 a）表明，自发面部自触手势（sFSTG）前后脑电活动的θ和β功率发生了显著变化。整个实验中EEG参数的变化动态表明，自发进行的面部皮肤自触可能调节工作记忆过程和同时发生的情绪过程。相反，如果检查员指示参与者触摸他们的脸，则不会发生这种前后EEG变化。这些发现是第一个神经生物学证据支持这一假设，即指向自身身体的运动可能履行调节功能。各个研究课题可能在神经生物学基础研究和临床环境水平上为人类行为提供有前途的见解。申请研究的目标如下：B）分析sFSTG的持续时间和位置与之前的脑电活动模式的关系，在sFSTG期间和之后，c）sFSTG特性的分析（左手vs右手;同侧相对于对侧面部区域）与sFSTG之前、期间和之后的脑电活动模式的关系，d）阐明关于目标（a）至（c）的sFSTG的性别特异性特征，以及e）阐明阻止参与者进行FSTG所引起的行为影响和脑电变化。将采用Grunwald（2014 a）的研究设计对20至35岁的56名男性和56名女性进行测试。将对19通道EEG记录的常规带宽进行频谱和小波分析。sFSTG的运动和皮肤接触动力学将由现有的微处理器加速度传感器记录。研究的总持续时间（包括实施、数据分析和手稿提交）为12个月。
