人类的社会活动是通过大脑各个区域的神经元活动的协同作用来实现的，这是由它们的连通性支持的。在本研究中，我们研究了以工作时间为代表的社会活动与使用弥散张量成像（DTI）量化的大脑连接之间的关联。在483名健康参与者中，使用3 T磁共振成像进行DTI分析，并计算工作时间，考虑有偿就业时间（“有偿工作”类别），家务劳动时间（“在家工作”类别）和学校相关学习时间（“学生”类别）。分析各组工作时间与DTI指标的相关性。内囊前肢（ALIC）和上级额枕束（SFO）的平均扩散率（MD）值与总工作时间呈负相关（ALIC：r=-0.192，p = 2.3 × 10−5; SFO：r=-0.161，p = 3.8 × 10-4）。我们还发现，ALIC和SFO的MD值与有偿工作类别的工作时间相关（ALIC：r=-0.211，p = 3.2 × 10-6; SFO：r=-0.163，p = 3.4 × 10-4），但与在家工作类别和学生类别的工作时间无关。这些结果表明，社会活动与白色物质的ALIC和SFO的微观结构。“为报酬而工作”和其他两种社会活动的主要区别似乎是动机的类型，例如，外部与内部。因此，ALIC和SFO的白色微结构可能与外部动机的社会活动有关。
Human social activities are realized by a synergy of neuronal activity over various regions of the brain, which is supported by their connectivity. In the present study, we examined associations between social activities, represented by work hours, and brain connectivity as quantified using diffusion tensor imaging (DTI). In 483 healthy participants, DTI analysis was performed using 3 T magnetic resonance imaging, and work hours were calculated, considering hours of paid employment (the “Work for Pay” category), hours of housework (the “Work at Home” category), and hours of school-related study (the “Student” category). The correlations between each class of work time and DTI indices were analyzed. The mean diffusivity (MD) values of the anterior limb of the internal capsule (ALIC) and the superior fronto-occipital fasciculus (SFO) were negatively correlated with total work hours (ALIC:r= -0.192,p= 2.3 × 10−5; SFO:r= -0.161,p= 3.8 × 10-4). We also found that the MD values of the ALIC and the SFO were correlated with work hours in the Work for Pay category (ALIC:r= -0.211,p= 3.2 × 10-6; SFO:r= -0.163,p= 3.4 × 10-4) but not with those in the Work at Home category or the Student category. These results suggest that social activity is associated with the white matter microstructure of the ALIC and the SFO. The main difference between “Work for Pay” and the other two social activities appears to be the type of motivation—for example, external versus internal. Therefore, the white matter microstructure of the ALIC and SFO may be related to externally motivated social activities.
