  1. přední část g. parahippocampalis – entorhinální kortex – příjem kognitivních a senzorických informací z asociačních kortikálních oblastí, přenáší tyto informace do hipp. pro konsolidaci a pak vrací zpět do asociačního kortexu, kde dochází ke kodování ve formě paměťových stop hippokampální formace – subiculum, vlatní hippocampus, gyrus dentatus, jednotlivé sektory se označují jako cornu ammonis fornix – přímé pokračování fibria, která přijímají axony ze subicula a hippocampu, vedou do předního hypothalamu, ncl mammillaris bilat. poškození hippokampu – ztráta deklarativní paměti, procedurální je zachována
