Upgrade of 3 Tesla magnetic resonance imaging system

磁共振成像（MRI）是认知神经科学的关键研究工具，对于了解健康和疾病中的人类大脑至关重要。核磁共振成像可以进行无创的全脑测量，让我们了解大脑的功能和结构。位于Universität德累斯顿技术大学的神经成像中心成立于2006年，当时正在使用的3台特斯拉核磁共振成像设备投入使用。在过去的14年里，这台核磁共振成像仪使心理学和医学院的研究小组能够进行具有国际竞争力的认知神经科学研究。MRI也是几个大型资助计划的关键测量技术，例如两个合作研究中心（SFB 940和TRR 265），以及广泛的个人项目资助。基于这些正在进行的资助计划，我们将专注于描述健康和疾病中认知控制和意志机制的总体研究问题。特别是，通过相互关联的计算和实验研究，我们将建立一个理论框架，研究大脑如何动态地施加认知控制，并使用元控制来快速适应不同任务和不断变化的环境之间的行动选择。我们将使用这个框架来开发成瘾行为、功能失调的学习过程、适应不良习惯的发展和认知控制受损的机制，如反应抑制失败，以及在行动选择过程中更普遍的前瞻性计划失败。这项研究计划的目的是推导出认知控制的机制理解，它在疾病中的失败，并为精神障碍开发基于机制的干预措施。

Magnetic resonance imaging (MRI) is a key research tool in the cognitive neurosciences and is critical for developing an understanding of the human brain in both health and disease. MRI allows for non-invasive, whole-brain measurements that inform us about brain function as well as brain structure. The Neuroimaging Centre at the Technische Universität Dresden was established in 2006 when the currently used 3 Tesla MRI was commissioned. Over the last 14 years, this MRI machine has enabled research groups at the faculties of psychology and medicine to perform internationally competitive, cognitive neuroscience research. MRI is also the key measurement technique within several large-scale funding initiatives, such as two collaborative research centres (SFB 940 and TRR 265), and a wide range of individual project grants. Based on these ongoing funding initiatives, we will focus on the overarching research question of delineating the mechanism of cognitive control and volition, both in health and disease. In particular, using interlinked computational and experimental studies, we will establish a theoretical framework of how the brain dynamically exerts cognitive control and uses meta-control to rapidly adapt its action selection between different tasks and changing contexts. We will use this framework to develop mechanistic accounts of addictive behaviour, dysfunctional learning processes, the development of maladaptive habits and impaired cognitive control such as response inhibition failures and more generally failures in forward planning during action selection. The aim of this research program is to derive a mechanistic understanding of cognitive control, its failures in disease and to develop mechanism-based interventions for mental disorders.
