Functional imaging studies investigating perception of depth rely solely on one type of depth cue based on non-natural stimulus material. To overcome these limitations and to provide a more realistic and complete set of depth cues natural stereoscopic images were used in this study. Using slow cortical potentials and source localization we aimed to identify the neural correlates of monocular and binocular depth cues. This study confirms and extends functional imaging studies, showing that natural images provide a good, reliable, and more realistic alternative to artificial stimuli, and demonstrates the possibility to separate the processing of different depth cues.
研究深度感知的功能成像研究仅基于非自然刺激材料依赖于一种深度线索。为了克服这些局限性并提供更真实和完整的深度线索集，本研究使用了自然立体图像。利用慢皮层电位和源定位，我们旨在识别单眼和双眼深度线索的神经关联。这项研究证实并扩展了功能成像研究，表明自然图像为人工刺激提供了一个良好、可靠且更逼真的替代方案，并证明了分离不同深度线索处理的可能性。
