11. Time’s up! Put Bell Ringer in Folder Today’s Agenda: Brain Physiology Graphic Organizer

12. The Human Brain **Only need to write down/summarize what is in BLUE

13. Cerebrum - The largest division of the brain. It is divided into two hemispheres, each of which is divided into four lobes. Cerebrum Cerebellum

14. Lobes of the Brain (4) Frontal Parietal Occipital Temporal http://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpg

15. Frontal Lobe

16. Lobes of the Brain - Frontal The Frontal Lobe of the brain is located at the front of the brain. It plays an integral role in the following functions/actions: - Emotions - Decision Making/Reasoning - Personality Modified from: http://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpghttp://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpg

17. Parietal Lobe (Pah-rye-eh-tal) Parietal Lobe

18. Lobes of the Brain - Parietal Lobe The Parietal Lobe of the brain is posterior to the Frontal lobe, but anterior to the Occipital lobe It plays a major role in the following functions/actions: -sensory information and cognition (Experiencing taste, smell, touch, pain, temperature, etc. signals and processing it.) Modified from: http://www.bioon.com/book/biology/whole/image/1/1-8.tif.jpghttp://www.bioon.com/book/biology/whole/image/1/1-8.tif.jpg

19. Occipital Lobe

20. Lobes of the Brain – Occipital Lobe The Occipital Lobe of the Brain is located in the back part of the brain (farthest from the eyes) Its primary function is the processes VISION and visual stimuli. Modified from: http://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpghttp://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpg

21. Temporal Lobe

22. Lobes of the Brain – Temporal Lobe The Temporal Lobes are the most lateral. They are located on the sides of the brain, above the ears They play an integral role in the following functions: - Hearing - Language Comprehension - Memory Formation Modified from: http://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpghttp://www.bioon.com/book/biology/whole/image/1/1- 8.tif.jpg

23. Cerebellum “little brain” Cerebellum

24. The cerebellum is located just above the brain stem and toward the back of the brain. It is relatively well protected from trauma compared to the frontal and temporal lobes and brain stem. Functions: - Coordination/ Balance - Muscle Tone

25. Brain Stem

26. The Brain stem consists of the midbrain, pons and medulla oblongata. It merges into the spinal cord. Functions: - attention - consciousness - breathing - sleeping - temperature **All information to and from our body passes through here on the way to and from the brain

29. Further Investigation Phineas Gage: Phineas Gage was a railroad worker in the 19th century living in Cavendish, Vermont. One of his jobs was to set off explosive charges in large rock in order to break them into smaller pieces. On one of these instances, the detonation occurred prior to his expectations, resulting in a 42 inch long, 1.2 inch wide, metal rod to be blown right up through his skull and out the top. The rod entered his skull below his left cheek bone and exited after passing through the anterior frontal lobe of his brain. Frontal

30. Remarkably, Gage never lost consciousness, or quickly regained it (there is still some debate), suffered little to no pain, and was awake and alert when he reached a doctor approximately 45 minutes later. He had a normal pulse and normal vision, and following a short period of rest, returned to work several days later. However, he was not unaffected by this accident. Frontal

31. Q: Recalling what you have just learned regarding the frontal lobe, what possible problems or abnormalities may Gage have presented with subsequent to this type of injury (remember the precise location of the rod through his brain)? A: Gage’s personality, reasoning, and capacity to understand and follow social norms had been diminished or destroyed. He illustrated little to no interest in hobbies or other involvements that at one time he cared for greatly. ‘After the accident, Gage became a nasty, vulgar, irresponsible vagrant. His former employer, who regarded him as "the most efficient and capable foreman in their employ previous to his injury," refused to rehire him because he was so different.’ Q: It is suggested that Gage’s injury inspired the development of what at one time was a widely used medical procedure. What might this procedure be, and how does it relate to Gage’s injury? A: The frontal lobotomy. This has been used with the intention to diminish aggression and rage in mental patients, but generally results in drastic personality changes, and an inability to relate socially. This procedure is largely frowned upon today, with the development of neurological drugs as treatments. Frontal
