在蜜蜂 [Apis mellifera] 视叶的髓质和小叶中记录到窄带或单色神经元。紫外、蓝色和绿色单位的光谱灵敏度与相应受体相似，但比相应受体更窄。颜色对手细胞记录在近端髓质中，主要受到紫外线激发并受到蓝色和绿色的抑制。很少发现被紫外线抑制的绿色和蓝色兴奋神经元。所有对手细胞在紫色区域表现出最大的敏感性变化。这些神经元的感受野是均匀的，每个点都被第一个波长激发，而另一个点则被抑制。多色神经元，即那些在几个波长范围内显示出明显的颜色依赖性响应但仅在 1 个波长范围内显示出主导响应的神经元，主要记录在小叶中。仅发现了以紫外线或绿色为主的多色细胞。它们的感受野显示出复杂的颜色依赖子结构，这些子结构不是同心排列的。两个神经元显示来自超过 1 个颜色通道的明确输入，但仍保持窄带。这些神经元在 2 个受体重叠的区域（即蓝绿色和紫色）反应最佳。与脊椎动物一样，颜色对立似乎在颜色整合中发挥着重要作用，尽管没有发现证据支持颜色与空间对立的组合。
Narrow band or monochromatic neurons were recorded in the medulla and lobula of the bee [Apis mellifera] optic lobe. The spectral sensitivities of UV, blue and green units were similar to, but narrower than those of the corresponding receptors. Color opponent cells were recorded in the proximal medulla and were predominantly UV excited and inhibited by blue and green. Green and blue excited neurons which were inhibited by UV were rarely found. All opponent cells showed a maximum sensitivity change in the violet region. The receptive fields of these neurons were homogeneous, each point being excited by the 1 wavelength and being inhibited by the other. Polychromatic neurons, i.e., those that showed clear color dependent responses in several wavelength regions but which showed a dominant response in only 1 wavelength range were recorded mainly in the lobula. Only UV or green dominated polychromatic cells were found. Their receptive fields show complex color dependent substructures which are not concentrically arranged. Two neurons showed definite inputs from more than 1 color channel but remain narrow band. These neurons respond best in the region of overlap of 2 receptors, i.e., bluish-green and violet. Color opponency appears to play a major role in color integration as in vertebrates, although no evidence supporting the combination of color with spatial opponency was found.
