Pigment granules without the properties of melanin are present in neurons of several districts (Nucleus ruber, Locus coeruleus, Ala cinerea) in the C.N.S. in Bos Taurus. The distinctive features of this pigment are autofluorescence, specifity of staining with Oil red O, Sudan Black and a strong P.A.S. positivity. The early pigment granules appear about at the end of the first year of life, their amount increases with age. The most rich pigment neurons are in the Nucleus ruber; in the neurons of the Substantia nigra, the pigment is very scanty also in the very old animals.
在金牛座的中枢神经系统中，几个区域（红核、蓝斑、灰翼）的神经元中存在不具有黑色素特性的色素颗粒。这种色素的显著特征是自发荧光、油红O染色特异性、苏丹黑染色特异性以及强烈的过碘酸雪夫反应阳性。早期色素颗粒大约在出生后第一年年底出现，其数量随年龄增长而增加。色素最丰富的神经元位于红核；在黑质神经元中，即使是非常年老的动物，色素也非常稀少。
