Presentation Transcript

  1. 2- Basal nuclei • 1- Caudate nucleus • 2- Lentiform nucleus • 3- Amygdaloid nucleus • 4- Claustrum nucleus • 5- Accumbens nucleus • 6- Substantia inominata

  2. Function of corpus striatum • storage of the movement orders that we learned before

  3. Amygdaloid nucleus

  4. Amygdaloid nucleus corticomedial central central basolateral basolateral

  5. Amygdaloid nucleus corticomedial Olfactory Autonomic centers in brain stem central central Sensory associating cortex of parietal and temporal lobes basolateral

  6. Parietal lobe

  7. Functins of amygdala • 1- exciting of amygdala in cat and monkey causes defense reaction • 2- in appetitive behavior • 3- has the most morphine receptors

  8. Exciting of amygdaloid

  9. Division of striatum based on phylogenetic development • 1- archistriatum (amygdaloid) • 2- paleostriatum/pallidum ( globus pallidus) • 3- neostriatum/striatum ( caudate +putamen)

  10. septal nucleus

  11. Septal nucleus Diagonal band of broca

  12. 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

  13. Claustrum

  14. Nucleus accumbens and substantia inominata ( ventral striatum)

  15. Accumbens nucleus Substantia inominata

  16. Limbic system Basal nuclei
