It can make fine visual distinctions because it is blessed with one million cones per square millimeter in its retina.
它的视网膜上每平方毫米有一百万个视锥细胞，所以它能分辨出很细微的视觉差别。
When they detect light, rods and cones pass the visual signal from nerve cell to nerve cell to the visual processing part of the brain.
当光线被这些感受器感受到时，杆状和锥状细胞就把视觉信号从一个神经细胞传到另一个神经细胞，一直传送到大脑负责成像处理的区域。
What's more, these chicken cones are distributed evenly throughout the retina, enhancing the birds' ability to see colors all around their visual field.
此外，这种鸡的锥体均匀的分布在整个视网膜内，加强了他们整个视觉系统辨别颜色的功能。
So in the case of the visual pathway, you start with the retina where rods and cones are connected by cells.
因而要理解所谓视觉通道，你首先应想到视网膜中的视杆细胞群和视锥细胞群之间也通过细胞连接。
This result means that UV wavelengths are seen as distinct colors by birds and that UV cones participate in a tetrachromatic visual system.
这个结果意味著，鹦鹉会把紫外光波长看成不同颜色，而且，紫外光锥细胞参与了四色色觉系统。
Blueberry and bilberry supply visual purple which nourishes rhodopsin which activates cones and rods.
