The dorsal accessory olive appears only sHghtiy above the level of the appearance of the ventral accessory nucleus as a small lamina of gray matter which continues upward as a rather narrow strand. At the level of appearance of the main mass of the inferior olivary nucleus it expands into a narrow flattened sheet which lies dorsal to the hilus of the inferior olivary nucleus. The main nucleus appears as the fourth ventricle begins to open in the form of a loop-shaped layer of gray matter, presenting a few simple reduplica-.
