最近的一项研究表明，腹侧纹状体的丘脑核可以解释为什么在线用户会在社交网络平台Facebook上花费时间。在这里，更高的活动的核神经元与获得声誉在社交媒体上。在本研究中，我们触及了一个相关的研究领域。我们记录了N = 62名参与者在五周内在智能手机上的实际Facebook使用情况，并将Facebook使用情况的汇总指标与脑桥核的灰质体积相关联。它似乎，特别是更高的日常频率检查Facebook上的智能手机与较小的灰质体积的脑桥核强有力地联系在一起。本研究提供了额外的支持，奖励方面的Facebook的使用。而且，它表明了在人类神经科学研究中包括真实的生活行为变量的可行性。
A recent study has implicated the nucleus accumbens of the ventral striatum in explaining why online-users spend time on the social network platform Facebook. Here, higher activity of the nucleus accumbens was associated with gaining reputation on social media. In the present study, we touched a related research field. We recorded the actual Facebook usage of N = 62 participants on their smartphones over the course of five weeks and correlated summary measures of Facebook use with gray matter volume of the nucleus accumbens. It appeared, that in particular higher daily frequency of checking Facebook on the smartphone was robustly linked with smaller gray matter volumes of the nucleus accumbens. The present study gives additional support for the rewarding aspects of Facebook usage. Moreover, it shows the feasibility to include real life behavior variables in human neuroscientific research.
