Seven color-opponent bipolar and 50 color-opponent amacrine cells were identified in the carp retina and their spectral responses examined by using procion-dye-filled micropipets for staining and recording. Four of the bipolar cells had a +R-G-and three a +Y-B-type chromatic center. Six of the bipolar cells showed hyperpolarizing non-color-opponent surrounds, while one +R-G-type cell had a +Y-RB-type surround. This cell showed the greatest complexity of all bipolar cells identified so far, and its spectral property strongly suggests the existence of an intimate relation between it and +Y-RB-type horizontal cells. Examination and classification of the 50 amacrine cells revealed that 17 belonged to the +R-G, 16 to the -R+G, 6 to the +Y-B, and 11 to the -Y + B type. Most of these cells showed non-color-opponent surrounds. Yet, the similarity of the chromatic arrangement of their centers with that of the ganglion cells shows that the four basic types of color channels are already in existence in the amacrine cells where they seem to originate.
在鲤鱼视网膜中识别出7个颜色拮抗双极细胞和50个颜色拮抗无长突细胞,并使用普施安染料填充的微电极进行染色和记录,以检测它们的光谱响应。其中4个双极细胞具有+R-G-型色中心,3个具有+Y-B型色中心。6个双极细胞表现出超极化非颜色拮抗的周边,而1个+R-G型细胞具有+Y-RB型周边。该细胞是迄今为止所识别的所有双极细胞中最复杂的,其光谱特性强烈表明它与+Y-RB型水平细胞之间存在密切关系。对50个无长突细胞的检测和分类显示,17个属于+R-G型,16个属于-R+G型,6个属于+Y-B型,11个属于-Y + B型。这些细胞中的大多数表现出非颜色拮抗的周边。然而,它们中心的颜色排列与神经节细胞的相似性表明,这四种基本类型的颜色通道在无长突细胞中似乎已经存在,而无长突细胞似乎就是这些通道的起源之处。
