During the further development to the brain of primates or to the human brain, certain developmental phenomena are continued. For example, in the vertebrate series one observes an increasing separation of modalities, which occurs first in the primordial brain, but later also in the spinal cord. In humans, this has progressed so far that separate axon bundles can be perceived in the spinal cord. Every neurology student has difficulty learning these many axon bundles, which have their own Latin names. The names are usually based on the places of origin and destination, as well as on the many axon connections between the individual substructures of the brain.

Furthermore, in the vertebrate series, an increase in signal divergence in the cerebellum and cortex is observed, combined with an increase in the size of all substructures involved. This is coupled with an increasingly differentiated perception of the external and internal environment.

In humans, there is a strong increase in the size of the pontocerebellum, which, as has been derived here, is associated with an equally strong increase in the ability to learn. Each newly added Purkinje group can learn a further complex signal. However, the neurons of the pontocerebellum projecting into the cortex are not able to create body images, because these axons transport complex signals. Therefore, body images only exist in the primary and secondary cortex regions. The tertiary cortex regions represent signal maps that will be different for each person and depend on which complex signals (terms) have been learned and in which order. This will be different from person to person and from region to region.

The question of the emergence of intelligence and thought was also not the focus of this monograph. It was only intended to show which algorithms are available to the vertebrate brain and how they have developed in the course of evolution. May further research be promoted by this monograph.
