of the inferior occipital or vice versa ; but in the human brain there is 

 room for all these unstable and mutually compensatory sulci to exist 

 in a well-developed form side by side. 



The expansion of the neopallium has far- reaching effects upon other 

 regions of the nervous system : the fibre systems connected with it 

 become more bulky, the cerebellum becomes larger, it* muMlr 

 peduncle the pons becomes so broad that it completely covers the 

 trapezoid bodies and extends down to the inferior olives. In 

 innumerable ways the whole nervous system is profoundly influenced 

 and modified in structure as the result, directly or indirectly, of the 

 attainment of the neopallium to the height of its perfection.
