Den hvide substans består af efferente (fraførende) og afferente (tilførende) fibre som arangeres i baner benævnt tracti eller fasciculi. Overordnet inddeles disse banner i tre typer:<br /> <br /> * Associationsbaner<br /> * Commissurale baner<br /> * Projektions baner<br /> <br /> === Associations baner ===<br /> Associations baner eller fibrebundter, er dels korte U-formede baner som forbinder cortex i nabo gyri, dels længere associations områder som forbinder cortex områder med større afstand. Associationsbaner er således baner der forbinder forskellige cortikale områder. De større associationsbaner er:<br /> * Fasciculus longitudinalis Inferior (FLI) <br /> * Fasciculus Longitudinal Superior (FLS) ([[Fasciculus Longitudinalis Superior &amp; Fasciculus arcuatus]])<br /> * Fasciculus Arcuatus (FA) som er en del af FLS<br /> * Fasciculus Uncinatus (FU)<br /> * Cingulum, som har sit forløb inden i gyrus Cinguli<br /> * Fornix<br /> * Fasciculus Occipito-Frontalis Inferior (FOFI)<br /> * Fasciculus Occipito-Frontalis Superior (FOFS)<br /> <br /> === Commissurale baner ===<br /> Commissurale baner der forbinder de to hjernehalvdele. Den største af de commissurale baner er:<br /> * Corpus Callosum, mens de mindre baner er:<br /> * Commissura anterior <br /> * Commissura posterior <br /> * Commissura Hippocampale<br /> <br /> === Projektions baner ===<br /> Projektionsbaner består afferente baner der fører impulser / information til cortex og efferente baner der fører impulser fra cortes til extracorticale mål. Eksempler på projektionsbaner omfatter:<br /> * [[Tractus Cortico-Spinalis]]<br /> * Tractus Cortico-Bulbaris<br /> * Visuelle baner<br /> * Auditoriske baner<br /> * Sensoriske thalamo-cortikale baner</div>
