Exciting of amygdaloid

Division of striatum based on phylogenetic development

1- archistriatum (amygdaloid) 2- paleostriatum/pallidum ( globus pallidus) 3- neostriatum/striatum ( caudate +putamen)

septal nucleus

Septal nucleus

Diagonal band of broca

Functions of septal nucleus

1- responsible for teta waves (slow waves 4-7 hertz) in REM and ordinary movement

2- transport memory from hipocumpus to prefrontal

3- inhibitor effects on lateral hypothalamus and reticular formation by MFB

4- exciting of this nucleus causes Euphoria and orgasm
