Humans live in a three-dimensional (3D) space and can perceive positions and shapes of objects in the space veridically based on visual information. This ability is crucial for recognizing the objects and for interacting with them. Numerous neuroimaging studies suggested that different brain regions are associated with the process of 3D information. However, these results are not consistent across the studies due to the wide variety of utilized tasks and visual stimuli. In this study, I conducted meta-analysis on studies of the functional magnetic resonance imaging (fMRI) about stereo 3D perception using the activation likelihood estimation (ALE) method. This fMRI meta-analysis aimed to answer which specific regions of the brain are associated with the 3D perception across the neuroimaging studies with different types of visual stimuli or tasks. After the screening, data of 405 healthy adult participants from 26 experiments of 16 studies were sampled in total for the analysis. Results of the analysis revealed large clusters activation associated with 3D information processing in the areas including middle occipital gyrus and cuneus, fusiform gyrus, superior parietal areas and middle frontal areas. The results of this meta-analysis provided concordant map of activation across the neuroimaging studies associated with the perception of the stereo 3D information. The observed results suggest that the process of the stereo 3D information requires increased resources of the brain compared to the process of the 2D information. Results of the analysis revealed large clusters activation associated with 3D information processing in the areas including middle occipital gyrus and cuneus, fusiform gyrus, superior parietal areas and middle frontal areas. The results of this meta-analysis provided concordant map of activation across the neuroimaging studies associated with the perception of the stereo 3D information. The observed results suggest that the process of the stereo 3D information requires increased resources of the brain compared to the process of the 2D information. Results of the analysis revealed large clusters activation associated with 3D information processing in the areas including middle occipital gyrus and cuneus, fusiform gyrus, superior parietal areas and middle frontal areas. The results of this meta-analysis provided concordant map of activation across the neuroimaging studies associated with the perception of the stereo 3D information. The observed results suggest that the process of the stereo 3D information requires increased resources of the brain compared to the process of the 2D information. The results of this meta-analysis provided concordant map of activation across the neuroimaging studies associated with the perception of the stereo 3D information. The observed results suggest that the process of the stereo 3D information requires increased resources of the brain compared to the process of the 2D information. The results of this meta-analysis provided concordant map of activation across the neuroimaging studies associated with the perception of the stereo 3D information. The observed results suggest that the process of the stereo 3D information requires increased resources of the brain compared to the process of the 2D information.
