Attention has been paid to the connection between morphogenesis and the synthesis of tissue structures with regard to their effects upon the functions and, on the other hand, their dependence on diseases and changes in blood circulation. A synthetic interpretation of the brain leads to the picture of a total ("ganzheitlich") order which, by itself, helps to explain the existence of a harmony. We have pointed to limitations in drawing parallels (in a biological sense) between human beings and animals. Above all, this becomes clear in the case of the Ncl. medio-dorsalis of the thalamus: Here is a functional system, the importance of which (for psycho-pathological conditions and disturbances) can be observed. Thereby, lacks of functions that are due to the dynamics of vital processes, can be explained. "Functional morphae" (Gestalten) are only those that are of a certain use. The variability of the building elements of the Ncl. medio-dorsalis is greater than its functions would require. However, there may be border-line cases, being explicable as a result of micro-evolution. The "change of forms" ("Formwandel") can finally help to illustrate certain pathological formations whose detailed interpretation is not entirely possible.
