Investigation of binocular three-dimensional perception with neural decoding techniques

点击翻译按钮获取中文摘要

The three-dimensional perception was investigated by neural decoding techniques with human cortical activity measured by functional magnetic resonance imaging (fMRI). The accuracy rates of decoding were compared between visual cortical areas to investigate the functions of the processing of binocular disparity. The results suggest that the relative disparity was represented in higher level of visual areas and the ventral stream areas concern with the binocular perception of three-dimensional shape rather than three-dimensional depth order of multiple objects.
