Bu çalışmada materyal olarak beşer adet yetişkin tavşan, kobay ve rat kullanıldı. Kobaylarda corpus callosum'un uzunluğu tavşan ve ratlardakinden daha fazla idi. İncelenen her üç türde de genu corporis callosi'nin fornixle birleşmediği gözlendi. Tavşan ve ratlarda genu'nun kalınlığı splenium'dan daha fazla iken kobaylarda splenium'un kalınlığı genu'dan fazla idi. Paraflocculus ventralis incelenen tüm materyallerde belirgin durumdaydı.

In this study, five rabbits, five guinea pigs and five rats were used as material and all the animals were adult. In guinea pigs, the length of corpus callosum was more than that in rabbits and rats. In all of the three species examined, it was observed that, genu corporis callosi did not join fornix. In rabbits and rats, the thickness of genu was greater than splenium, whereas in guinea pigs the thickness of splenium, was greater than genu. Paraflocculus ventralis was prominent in both materials examined.
