2. 2 divisions of the nervous system PNS – Peripheral Nervous System CNS – Central Nervous System – brain, spinal cord

3. brain 3 main divisions of brain – hindbrain; midbrain; forebrain

4. hindbrain a number of important fiber tracts project through the hindbrain into higher brain regions

5. hindbrain a number of important fiber tracts project through the hindbrain into higher brain regions – medulla

6. hindbrain a number of important fiber tracts project through the hindbrain into higher brain regions – Medulla Reticular formation – NE; locus coerulus - 5-HT (serotonin); raphe nuclei

7. medulla hindbrain

8. a number of important fiber tracts project through the hindbrain into higher brain regions – medulla – Pons -raphe -

9. hindbrain a number of important fiber tracts project through the hindbrain into higher brain regions – medulla – pons – cerebellum

10. medulla hindbrain

11. midbrain Sensory information Reward – Ventral tegmental area movement – substantia nigra -

12. forebrain cerebral cortex subcortical structures

13. forebrain Cerebral cortex – role of convolutions

15. 4 lobes of cerebral cortex frontal

16. parietal temporal occipital

17. 4 lobes of cerebral cortex frontal parietal

18. frontal parietal temporal occipital

19. 4 lobes of cerebral cortex frontal parietal temporal

20. frontal parietal temporal occipital

21. 4 lobes of cerebral cortex frontal parietal temporal occipital

22. frontal parietal temporal occipital

23. Some subcortical structures thalamus

24. The thalamus communicates with much of the cerebral cortex - serving as a sensory and motor information relay.

25. Some subcortical structures thalamus hypothalamus – important for hormonal release – also major DA projections

26. Some subcortical structures thalamus hypothalamus limbic system – important for emotion; learning and memory; reward; major DA pathway

28. Some subcortical structures thalamus hypothalamus limbic system basal ganglia – important for movement; major DA pathway that originates at substantia nigra terminates here

31. Major DA pathways mesolimbic – reward, emotion, etc nigrostriatal – important for movement; Parkinsons Disease – degeneration of the DA neurons in this pathway tuberofundibular - hypothalamus

34. NE – arousal, depression, also the NT in part of the sympathetic NS

35. 5HT – imp in sleep, depression, aggression (maybe)

36. basal forebrain, hippocampal, midbrain nuclei PNS – neuromuscular junction, sympathetic ns, parasympathetic ns
