Personality neuroscience integrates techniques from personality psychology and neuroscience to elucidate the neural basis of individual differences in cognition, emotion, motivation, and behavior. This endeavor is pertinent not only to our understanding of healthy personality variation, but also to the aberrant trait manifestations present in personality disorders and severe psychopathology. In the current review, we focus on the advances and limitations of neuroimaging methods with respect to personality neuroscience. We discuss the value of personality theory as a means to link specific neural mechanisms with various traits (e.g., the neural basis of the "Big Five"). Given the overlap between dimensional models of normal personality and psychopathology, we also describe how researchers can reconceptualize psychopathological disorders along key dimensions, and, in turn, formulate specific neural hypotheses, extended from personality theory. Examples from the borderline personality disorder literature are used to illustrate this approach. We provide recommendations for utilizing neuroimaging methods to capture the neural mechanisms that underlie continuous traits across the spectrum from healthy to maladaptive.

人格神经科学整合了人格心理学和神经科学的技术，以阐明认知、情感、动机和行为方面个体差异的神经基础。这一努力不仅与我们对健康人格变异的理解相关，也与人格障碍和严重精神病理学中出现的异常特质表现相关。在当前的综述中，我们关注神经成像方法在人格神经科学方面的进展和局限性。我们讨论人格理论作为将特定神经机制与各种特质（如“大五”人格的神经基础）联系起来的一种手段的价值。鉴于正常人格的维度模型与精神病理学之间的重叠，我们还描述了研究人员如何沿着关键维度重新概念化精神病理障碍，进而从人格理论出发提出具体的神经假说。边缘型人格障碍文献中的例子用于说明这种方法。我们提供了利用神经成像方法来捕捉从健康到适应不良整个范围内连续特质背后的神经机制的建议。（PsycINFO数据库记录）
