Further, between the individual gyri of the non- medullated regions, bands of association fibres gradually ripen, con- necting the individual gyri with others near them and also with gyri at a distance. By means of the corpus callosum the gyri in one hemisphere are connected with those of the opposite hemisphere. Flechsig, on account of the marked predominance of association systems in these areas, has designated them association centres of the cerebral cortex. * He does not, as did Meynert, believe Fig. 676.—View of the niedijil surface of the left cerebral hemisphere, showing sense centres and association centres.
