2- Basal nuclei • 1- Caudate nucleus • 2- Lentiform nucleus • 3- Amygdaloid nucleus • 4- Claustrum nucleus • 5- Accumbens nucleus • 6- Substantia inominata
Function of corpus striatum • storage of the movement orders that we learned before
Amygdaloid nucleus corticomedial central central basolateral basolateral
Amygdaloid nucleus corticomedial Olfactory Autonomic centers in brain stem central central Sensory associating cortex of parietal and temporal lobes basolateral
Functins of amygdala • 1- exciting of amygdala in cat and monkey causes defense reaction • 2- in appetitive behavior • 3- has the most morphine receptors
Division of striatum based on phylogenetic development • 1- archistriatum (amygdaloid) • 2- paleostriatum/pallidum ( globus pallidus) • 3- neostriatum/striatum ( caudate +putamen)
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
Nucleus accumbens and substantia inominata ( ventral striatum)
Accumbens nucleus Substantia inominata
Limbic system Basal nuclei
