1. Brain Anatomy Regions and their functions

2. 4 major regions Cerebral hemispheres Diencephalon Brain stem Cerebellum

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

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

5. Central sulcus Precentral gyrus = primary motor

6. Primary Motor Cortex Precentral gyrus

7. Premotor Cortex Learned motor skills

8. Broca’s area

9. Sensory Areas

10. Primary Somatosensory Cortex Postcentral gyrus

11. Somatosensory Association cortex Posterior to postcentral gyrus

12. Visual area Extreme posterior tip of occipital lobe

13. Visual Association Area Surrounds the visual area… determines what you are seeing –i.e. 2 pretty eyes, short hair, ears… its Rihanna!

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

15. 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

16. Diencephalon 3 paired structures Thalamus Hypothalamus Epithalamus

17. 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.

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

19. 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

20. Epithalamus Pineal gland – melatonin hormone

21. Brain Stem
