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.
最近的一项研究表明，腹侧纹状体的伏隔核与解释在线用户在社交网络平台Facebook上花费时间的原因有关。在这里，伏隔核的较高活动与在社交媒体上获得声誉有关。在本研究中，我们涉足了一个相关的研究领域。我们记录了62名参与者在五周时间里通过智能手机实际使用Facebook的情况，并将Facebook使用的汇总指标与伏隔核的灰质体积进行了关联。结果发现，特别是在智能手机上每天查看Facebook的频率较高与伏隔核较小的灰质体积密切相关。本研究为Facebook使用的奖励方面提供了额外支持。此外，它还表明了在人类神经科学研究中纳入现实生活行为变量的可行性。
