我们利用猕猴初级视觉皮层第4C层的ln输入模型来验证第4C层棘星状神经元的P和m输入的前馈收敛足以解释所观察到的感受野大小和对比敏感度随层深度的逐渐变化的假设。突触后神经元的树突在M-和p -输入区之间的重叠足以解释4C层下三分之二的变化，而4C层上更快速的变化通过提出两个不同的M-输入来匹配，这些M-输入在上4C α部分重叠。1998爱思唯尔科学有限公司版权所有。
A model of LGN-input to layer 4C of macaque primary visual cortex has been used to test the hypothesis that feedforward convergence of P- and M-inputs onto layer 4C spiny stellate neurons is sufficient to explain the observed gradual change in receptive field size and contrast sensitivity with depth in the layer. Overlap of dendrites of postsynaptic neurons between M- and P-input zones proved sufficient to explain change in the lower two-thirds of layer 4C, while more rapid change in upper 4C was matched by proposing two different M-inputs with partial overlap in upper 4C alpha.
