情绪障碍是许多精神障碍的核心问题,尤其是恐惧、焦虑和创伤后。
和情绪障碍。因此,描述与情绪信息处理能力相关的主要神经功能机制是一项艰巨的任务。
关键问题是心理健康和医疗保健。之前的研究试图在未来几年重新定义人类情感的神经生理学特征。
认知、神经科学和实验室的发展一直受到一些概念上的障碍和障碍。
方法论框架有助于研究在特定背景下的复杂情绪反应,以及在冲突情绪下的反应。
目前的情况是,这项新提出的研究项目建立了一种将电生理技术与生物医学相结合的全新的技术体系。
录音在时间和精度上都很高,与功能正常的大脑和成像相比,在空间和精度上也是很高的。
这种方法被称为稳态或潜在的频率标记,它实现了刺激的特异性、时间、空间和空间。
解决方案覆盖了整个大脑。它是计算机中独一无二的解决方案,它使研究人员能够更好地识别不同的大脑和网络。

英文摘要
Project Summary
Emotional dysfunction is at the core of many psychiatric disorders, in particular fear, anxiety, post-traumatic,
and mood disorders. Describing the neural mechanisms associated with emotional processing is therefore a
critical issue in mental health care. Previous attempts to define the neurophysiology of human emotions in the
cognitive neuroscience laboratory have been hampered by the unavailability of conceptual and
methodological frameworks for studying complex emotional responses in context and with conflicting
information present. The proposed research establishes a novel technique for combining electrophysiological
recordings, high in temporal precision, with functional brain imaging, which is high in spatial precision. This
approach, called steady-state potential frequency-tagging, achieves stimulus specificity, temporal, and spatial
resolution across the whole brain. It is unique in that it allows researchers to identify distinct brain networks
selectively activated by different elements of a complex visual scene—even when the elements are spatially
overlapping and accompanied by stimulation in other sensory modalities. We combine this innovative
approach with a novel conceptual framework that considers changes in visual perception an active part of an
observer’s emotional response, to address the following Aims: (1) We characterize the large-scale brain
dynamics mediating the emotional response to an element that is embedded in a complex visual array. (2)
We determine how conflicting appetitive and aversive information, visual and auditory, affects these brain
dynamics. (3) Finally, we translate this novel method to socially anxious observers, testing mechanistic
hypotheses regarding the interactive effects of trait anxiety and chronic stress on short-term reactivity to
emotional challenge. The long-term clinical implications of the proposed research are manifold: For
diagnostic assessment and for monitoring treatment efficacy, a quantitative brain-based marker of emotional
engagement opens avenues for objectively evaluating pre- to post-treatment changes in appetitive/aversive
neural reactivity. It also enables measuring neural circuit function to enable quantitative measurements of
specific psychopathology and for identifying treatment targets in a personalized medicine framework.
