Abstract: | Summary The embryological fact (Kallén) that hyperstriatum, neostriatum and archistriatum in birds are homologous to the neopallium, palaeostriatum primitivum and augmentatum to the basal ganglions of the mammals, is made probable by recent results in the fields of morphology, physiology and animal psychology.The differentiation and form of the neopallial parts of the birds brain is not produced by a surface development, as in mammals, but in a three dimensional structure of the hemisphere, by mass in birds.This differentiation is strongly pronounced in highly cerebralized forms, and the stratified arrangement of the elements is to be interpreted as a structure of integration.With regard to function and organization, the neopallium of birds is strictly comparable to that of mammals. |
