摘要:

The nuclear volume in cells of the subfornical organ ofRana esculentashows a cyclic annual size change. It is pronounced both in the so‐called Gomori‐positive cells and the ependymal covering of the organ. There appears a maximum in April in the epen‐dyma and in May in the Gomori‐positive cells. The amount of neurosecretory material present in the subependymal layer also shows a maximum in April.
