Social media is pervasively used in our life. There is a research hypothesis that the information in social media will cause readers' addiction, insomnia, and inability to pay attention, thus reducing the efficiency of learning and working. The aim of this research is to thoroughly investigate the effects of social media on the human brain using neuroimaging techniques and to predict these effects using genetic data.
Finally, 77 patients were enrolled, and to study this problem, we integrated multimodal MRI, longitudinal design, and genotype sampling. Cerebral blood flow (CBF), functional connectivity (FC), and white matter integrity were all reflected using multimodal MRI. The longitudinal design included short-term and long-term social media tasks as well as MRI scanning at baseline, after the short-term task, and after the long-term task. APOE and BDNF genotypes were sampled for genotypes. A group of participants were enrolled in a control group who read science fiction on their smartphones.
