Neurobiological correlates of speech production influenced by different emotions

语言的研究是一个快速发展和惊人的研究领域。然而，到目前为止，我们对大脑如何协调产生语音的复杂过程以及我们的大脑如何将语音的产生与情感处理等其他过程联系起来知之甚少。该项目将重点关注不同的情绪信息对单个单词产生的不同阶段的影响。我们的目标是通过在功能磁共振成像测量过程中使用不同的任务来表征注意力，感知，认知和情感之间的潜在相互作用，因为这种方法代表了一个很好的机会来研究几乎每个语言产生水平的大脑过程。在第一个实验中，受试者将被要求命名一个单一的图片，同时忽略一个中性或情感价（积极或消极）干扰。通过这项任务，我们将能够研究概念，词汇和后词汇过程。在第二个实验中，我们将使用停止信号任务，受试者将再次命名一张图片，但偶尔不得不抑制他们的反应，因为停止信号是中性的，积极的或消极的。在这里，我们更愿意进入感知过程以及自我监控，使人类能够流利地说话，几乎没有错误。有了这些数据，我们将更近距离地观察不同的神经相关和网络，这些神经相关和网络使我们能够流畅地发出语音，即使我们被不同的情绪信息分散注意力。总的来说，我们的目标是通过使用功能性神经影像学检查空间和连接相关的大脑特征。通过这些结果，我们希望阐明异质性结果和高度争议的过程，并根据语言和情感相互作用的潜在神经相关性回答问题。

The investigation of language is a fast growing and amazing research area. However, until now little is known how our brain coordinates the complex processes of producing speech and how our brain connects the production of speech with other processes like emotional processing. The project will focus on the influence of different emotional information on the different stages of single word production. We aim to characterize potential interactions between attention, perception, cognition and emotion by using to different tasks during fMRI measurement as this approach represents a great opportunity to investigate brain processes at nearly every level of language production. In the first experiment, subjects will be asked to name a single picture while ignoring a neutral or emotionally valent (positive or negative) distractors. With this task we will be able to investigate conceptual, lexical and post-lexical processes. In the second experiment, we will use a stop-signal task where subjects will again name a single picture but occasionally have to inhibit their response because of a stop-signal that is either neutral, positive or negative. Here, we rather step into perceptual processes as well as the self-monitoring that enables humans to speak fluently with nearly no errors. With these data, we will have a closer look at different neural correlates and networks that enable us to produce speech fluently even if we are distracted by different emotional information. Overall, we aim to examine the spatial and connectivity related cerebral characteristics by using functional neuroimaging. With the results we hope to shed light on heterogeneous results and highly debated processes as well as answer questions according the underlying neural correlates of the interaction of language and emotion.
