this suggest that the antikynurenine effect of metabolites of kynurenine ( kynurenines ) is related to different brain structures , i.e . kynurenic acid predominantly affects structures adjacent to ventricles ( e.g . hippocampus , caudate nucleus ) while picolinic and anthranilic acids act on other brain structures or the periphery .
