This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Affective instability is a core feature of borderline personality disorder (BPD). It may be associated with significant functional impairment, high rates of service utilization, and negative clinical outcomes. This symptom may be related to an underlying disturbance in the neural processing of emotional stimuli. A recent development in the study of neurobilogical aspects of emotion processing involves exposing a subject to emotional stimuli in functional magnetic resonance imaging. This type of paradigm is consistently associated with activation of subcortical and neocortical brain regions known to be involved in emotional experience and processing of emotional information. Patients with affective disorders exhibit altered responses in several of these brain regions, including amygdala, and anterior cingulate, orbitofrontal and dorsolateral prefrontal cortices. A particularly important functional relationship for emotion regulation may exist between the amygdala and anterior cingulate cortex in these disorders in these disorder. In contrast, the pattern of regional brain activation to emotional stimuli has not been well-investigated in BPD. This application proposes to use fMRI to initiate a pilot study of regional brain response to emotional stimuli, with the prediction that BPD patients will show differences in the activation of areas of the amygdala and cingulate cortex compared to normal controls. Results from this study will be utilized to later examine the clinical specificity of this hypothesized brain brain dysfunction for the symptoms (ie within diagnostic category) and for the diagnosis (ie across diagnostic category) of BPD, and to characterize the temporal and spatial dynamics of emotion processing disturbance in a frontolimbic model of affective instability.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 情感不稳定是边缘型人格障碍（BPD）的核心特征。 它可能与严重的功能障碍、高服务利用率和负面的临床结果有关。 这种症状可能与情绪刺激的神经处理的潜在紊乱有关。 情绪处理的神经生物学方面的研究的最新进展涉及在功能磁共振成像中将受试者暴露于情绪刺激。 这种类型的范式始终与已知参与情绪体验和情绪信息处理的皮质下和新皮质大脑区域的激活相关。 患有情感障碍的患者在其中几个大脑区域表现出反应改变，包括杏仁核、前扣带皮层、眶额叶和背外侧前额叶皮质。 在这些疾病中，杏仁核和前扣带皮层之间可能存在对于情绪调节特别重要的功能关系。 相比之下，BPD 中大脑区域对情绪刺激的激活模式尚未得到充分研究。 该申请建议使用功能磁共振成像来启动区域大脑对情绪刺激的反应的初步研究，并预测与正常对照相比，BPD 患者的杏仁核和扣带皮层区域的激活会出现差异。 这项研究的结果将用于稍后检查这种假设的脑功能障碍对于 BPD 症状（即在诊断类别内）和诊断（即跨诊断类别）的临床特异性，并表征 BPD 的时间和空间动态。情感不稳定的额边缘模型中的情绪处理障碍。
