Early differentiation of the human retina. A neurohistological study.
A series of retinas from 30 human embryos, ranging in total length from 10 to 40 mm (i.e., to the end of gestation month 2), were successfully stained by the Golgi method and then examined and compared with routinely stained specimens from pertinent stages. Two more series impregnated with other silver methods were used as controls. In the results we try to clarify some difficult points in the literature on the subject.
