Gap junctions have been shown to electrically couple cone photoreceptors: coupling blurs the image coded by cones, but this loss is offset by a decrease in noise. Electrical coupling thus improves the resolution of signals distributed across groups of cells.
耦合会模糊视锥细胞编码的图像,但这种损失会因噪声降低而得到补偿。因此,电耦合提高了分布在细胞群中的信号分辨率。
