The aim of this study is to compare stereoscopic 3D based and 2D based educational contents for long-term memoriza- tion using electroencephalogram (EEG) signals. Sixty eight healthy young adults were equally divided into 2D group and stereoscopic 3D (S3D) group in such a way that their fluid intelligence and age were controlled between groups. S3D and 2D groups were exposed to S3D based and 2D based educational contents, respectively, for learning complex human anatomy concepts. The duration of contents was 30 minutes long and exactly after two months of retention they were asked to take a memory recall test of twenty multiple choice questions. The EEG signals were recorded during the recall session. The behavioral responses of both groups were not signifi- cant (p>0.05). However, the EEG source analysis revealed significant differences between 2D and S3D groups for long-term memorization (p<0.05) in the BA 7, BA 10, BA 11, and BA 25. The recall of S3D contents involved wide- spread brain neuronal network as compared to 2D contents. In conclusion, human brain processed the S3D contents differently for memorization than 2D contents. The differ-ences may be due to depth perception in S3D contents.
