2. Brain Anatomy Regions and their functions

3. By By Anthony

4. Mr. Verdi has a new favorite student…

5. Hippocampus and Amygdala

6. 4 major regions • Cerebral hemispheres • Diencephalon • Brain stem • Cerebellum

10. Cerebral Hemispheres • Right and Left  Superior part of brain • Most of mass of the brain • Shallow groove = sulcus • Elevated area by groove = gyrus

11. Cerebral Cortex • .125 inch thick… 40% of brain mass • Motor areas • Sensory areas • Association areas • Contralateral control

13. Central sulcus • Precentral gyrus = primary motor

14. Primary Motor Cortex • Precentral gyrus • Controls voluntary movement

15. Premotor Cortex • Learned motor skills

16. Broca’s area • Speech! Left hemisphere Broca's area and Wernicke's area are connected by a bundle of nerve fibers called the arcuate fasciculus. Damage to the arcuate fasciculus causes a disorder called conduction aphasia. People with conduction aphasia can understand language, but their speech does not make sense and they cannot repeat words.

17. Primary Somatosensory Cortex • Postcentral gyrus • Right hemisphere gets information from left, and upside down

18. Somatosensory Association cortex • Posterior to postcentral gyrus

19. Visual area • Extreme posterior tip of occipital lobe

20. Visual Association Area • Surrounds the visual area… determines what you are seeing • i.e. 2 pretty eyes, long hair, ears… its Zooey !

21. Auditory Areas • Top of temporal lobe = primary auditory area • Posterior of temporal lobe = auditory association area

22. Olfactory cortex •  primitive brain new functions • Rhinencephalon = Memory! • Why we remember smell of Grandma’s old smoky apartment, with dentures and those weird mints now only seen at midlevel restaraunts

23. Diencephalon • 3 paired structures • Thalamus • Hypothalamus • Epithalamus

24. Thalamus • Large number of nuclei • “Afferent impulses from all senses and all parts of the body converge on the thalamus • Includes sensory, visceral, emotional, etc.

25. Hypothalamus 7 functions 1.) Autonomic control center 2.) Center for emotional response 3.) Body Temperature Regulation

26. Hypothalamus 4.) Regulation of Food Intake 5.) Regulation of Water balance and thirst 6.) Regulation of sleep-wake cycles 7.) control of endocrine system functioning

27. Epithalamus • Pineal gland – melatonin hormone

28. Brain Stem

29. Midbrain

30. Pons

31. Medulla Oblongata

32. Medulla Oblongata • Cardiovascular center • Respiratory center • Various other centers

33. Cerebellum
