Relationship between white matter microstructure and work hours

Human social activities are realized by a synergy of neuronal activity over various regions the brain, which is supported their connectivity. In present study, we examined associations between activities, represented work hours, and brain connectivity as quantified using diffusion tensor imaging (DTI). 483 healthy participants, DTI analysis was performed 3 T magnetic resonance imaging, hours were calculated, considering paid employment (the “Work for Pay” category), housework at Home” school-related study “Student” category). The correlations each class time indices analyzed. mean diffusivity (MD) values anterior limb internal capsule (ALIC) superior fronto-occipital fasciculus (SFO) negatively correlated with total (ALIC: r = -0.192, p 2.3 × 10?5; SFO: -0.161, 3.8 10-4). We also found that MD ALIC SFO in Work Pay category -0.211, 3.2 10-6; -0.163, 3.4 10-4) but not those Home or Student category. These results suggest associated white matter microstructure SFO. main difference other two appears to be type motivation—for example, external versus internal. Therefore, may related externally motivated activities.
