A two-eye visual environment is used in training a network of BCM neurons. We study the effect of misalignment between the synaptic density functions from the two eyes, on the formation of orientation selectivity and ocular dominance in a lateral inhibition network. The visual environment we use is composed of natural images. We show that for the BCM rule a natural image environment with binocular cortical misalignment is sufficient for producing networks with orientation-selective cells and ocular dominance columns. This work is an extension of our previous single cell misalignment model Shouval et al., 1996.
在训练BCM神经元网络时使用双眼视觉环境。我们研究了来自双眼的突触密度函数之间的错位对侧向抑制网络中方向选择性和眼优势形成的影响。我们使用的视觉环境由自然图像组成。我们表明，对于BCM规则，具有双眼皮质错位的自然图像环境足以产生具有方向选择性细胞和眼优势柱的网络。这项工作是我们之前的单细胞错位模型（Shouval等人，1996年）的扩展。
