THE NEOPALLIUM. 359 



many aspects, a corresponding number and variety of association 

 tracts in his brain will be developed and fixed through use and will 

 be ready for the correlation of the experience of later years. Either 

 in the schoolroom, on the playground or in vacation time a richness 

 of experience must supply the association centers with the condition 

 for their high organization. Without this there can be in later 

 years no richness of mental life and no great power of research, 

 invention or constructive statesmanship. So on the moral side, 

 the realities of human relationships must come into the experience 

 of the youth during the period of plasticity of his brain if he is to 

 rise to the higher planes of moral hfe. 



DEMONSTRATION OR LABORATORY WORK. 



1. Dissect the brain of a cat, dog, sheep or man, working out the 

 relations of the neopallium to the archipallium and corpus striatum. 

 With the aid of figures in a larger text-book or atlas trace the limits 

 of the neopallium in man and the chief gyri and sulci and the location 

 of the senso-motor and association areas. 



2. As far as time and material permit, the structure of the cortex, 

 the course of projection and commissural fibers and the arrangement 

 of association bundles may be studied in Golgi or Weigert sections of 

 a mammalian brain.
