人们似乎从他们是独特的、特殊的、与大众分离的感知中获得内在的满足，这被称为独特性需求（NFU）。NFU是一种普遍的人类特征，沿着一种倾向，即遵从他人的信仰和态度以及社会规范。我们使用基于体素的形态测量和问卷调查来确定健康男性（94例）和女性（91例;年龄，21.3± 1.9岁）的个体NFU及其与脑结构的关系。个体NFU与一簇较小的灰质体积相关，包括（a）左侧颞中回、左侧上级颞回和左侧上级颞沟（STS）;（B）扣带回前部的背侧部分和扣带回中部的前部;（c）右侧额下回和中央前回的腹侧部分。单个NFU还与主要包括胼胝体的群集的较大白色物质浓度相关。这些结果表明，NFU的变化反映了病灶区域的灰和白色物质结构。这些发现表明了个体NFU的生物学基础，分布在大脑的不同灰质和白色物质区域。
People appear to derive intrinsic satisfaction from the perception that they are unique, special, and separable from the masses, which is referred to as a need for uniqueness (NFU). NFU is a universal human trait, along with a tendency to conform to the beliefs and attitudes of others and social norms. We used voxel-based morphometry and a questionnaire to determine individual NFU and its association with brain structures in healthy men (94) and women (91; age, 21.3±1.9years). Individual NFU was associated with smaller gray matter volume of a cluster that included areas in (a) the left middle temporal gyrus, left superior temporal gyrus, and left superior temporal sulcus (STS); (b) the dorsal part of the anterior cingulate gyrus and the anterior part of the middle cingulate gyrus; and (c) the right inferior frontal gyrus and the ventral part of the precentral gyrus. Individual NFU was also associated with larger white matter concentration of a cluster that mainly included the body of the corpus callosum. These findings demonstrated that variations in NFU reflect the gray and white matter structures of focal regions. These findings suggest a biological basis for individual NFU, distributed across different gray and white matter areas of the brain.
