建立了立体视觉和3D表面感知后期的层流皮质模型，并进行了模拟。该模型描述了单眼和双眼定向过滤的初始阶段如何与外侧膝状核和皮质区域V1、V2和V4的3D边界形成和表面填充的后期阶段相互作用。特别是，它详细说明了V1和V2中的第4层、第3B层和第2/3A层之间的相互作用如何有助于立体视觉，并阐明了双目和单目信息如何组合形成3D边界和表面表示。在此过程中，该模型对视差能量模型进行了修改和显著扩展。给出了心理物理数据的神经解释，涉及：双眼掩蔽的对比度变化和对应问题，眼睛间对比度差异对立体视的影响，Panum极限情况，威尼斯盲视，极性反转立体图的立体视，达芬奇立体视，以及各种亮度错觉。通过将生理学与心理物理学联系起来，该模型提供了关于层状皮质结构的新的功能洞察和预测。(C)2003爱思唯尔科学有限公司。保留所有权利。
A laminar cortical model of stereopsis and later stages of 3D surface perception is developed and simulated. The model,describes how initial stages of monocular and binocular oriented filtering interact with later stages of 3D boundary formation and surface filling-in in the lateral geniculate nucleus and cortical areas V1, V2, and V4. In particular, it details how interactions between layers 4, 3B, and 2/3A in V1 and V2 contribute to stereopsis, and clarifies how binocular and monocular information combine to form 3D boundary and surface representations. Along the way, the model modifies and significantly extends the disparity energy model. Neural explanations are given for psychophysical data concerning: contrast variations of dichoptic masking and the correspondence problem, the effect of interocular contrast differences on stereoacuity, Panum's limiting case, the Venetian blind illusion, stereopsis with polarity-reversed stereograms, da Vinci stereopsis, and various lightness illusions. By relating physiology to psychophysics, the model provides new functional insights and predictions about laminar cortical architecture. (C) 2003 Elsevier Science Ltd. All rights reserved.
