1 © West Educational Publishing 500 pound gorilla vs. 150 pound human

2 © West Educational Publishing How much do each of their brains weigh?

3 © West Educational Publishing Gorilla’s Brain = 1 pound Human’s Brain = 3 pounds

4 © West Educational Publishing Brain to Body Ratio 1:500 Brain to Body Ratio 3:150 If the human brain were of the same ratio as the gorilla’s, our brain would only weigh 5 ounces!

5 © West Educational Publishing OBJECTIVES: ● List consequences that can occur if the frontal lobe is damaged. ● Discover how verbal tasks interfere with right-handed motor skills – results of the Kinsbourne & Cook study (1971) ● Describe condition known as agnosia. ● Identify which parts of the brain were activated while viewing a video clip.

7 © West Educational Publishing FRONTAL LOBE CORE OF THE PERSONALITY

8 © West Educational Publishing FRONTAL LOBE If damaged, here’s a likely list of consequences: Inappropriate emotions Socially unacceptable behaviors (usually meaning fewer inhibitions) Inability to make long-range plans Easily distracted Difficulty integrating facts

9 © West Educational Publishing FRONTAL LOBE Example of a person with frontal lobe damage: He/she goes into the bedroom to make the bed, becomes distracted by the wallpaper, which he/she decides need to be changed, and rips it down!

10 © West Educational Publishing Hemisphere Dominance Demonstration

11 © West Educational Publishing Kinsbourne & Cook Study Subjects completed a verbal task while balancing a wooden rod on either the left or the right finger. Subjects were able to balance the rod longer on their left finger than on their right. Apparently, a verbal task (left-hemisphere skill) interferes with a right-handed motor skill (a left-hemisphere motor-strip task).

12 © West Educational Publishing Imagine gazing at a running shoe, taking in the laces and the color of the stripes, drawing the shoe on a big piece of paper with crayons, yet not being able to identify the object as a shoe…

13 © West Educational Publishing AGNOSIA…. AKA: Mindblindness - Results from brain injury

14 © West Educational Publishing If a person with agnosia is able to feel the object (however), he/she can then name the object without hesitation. Several senses need to be stimulated in order for a whole picture to develop. Some people develop facial agnosia, where they may not be able to identify their own family members until they hear their voices.

15 © West Educational Publishing OBJECTIVES: ● Describe what the Broca’s area is and results if the area is damaged. ● Discover which of your motor strips is dominant. ● Describe the Mozart effect. ● Name/list famous left-handed people. ● Describe what split brain is & how it affects a person with a split brain.. ● Discover how to utilize both sides of the brain while taking notes.

16 © West Educational Publishing Broca’s Area Wernicke’s Area

17 © West Educational Publishing Question: If both a woman and a man have a stroke that damages this area (Broca’s area), who is more likely to recover?

18 © West Educational Publishing Question: If both a woman and a man have a stroke that damages this area (Broca’s area), who is more likely to recover? Brain imaging techniques reveal that many women process speech and language in both hemispheres, so a woman is much more likely to recover her verbal skills.

19 © West Educational Publishing WERNICKE’S area is located in the left temporal lobe and is involved in the process of understanding (processing) words we hear spoken.

20 © West Educational Publishing Exploration – Motor Strip Dominance Make tallies under these categories: Left Right No Preference when I ask you the following questions……. (Go with what comes first/naturally.)

21 © West Educational Publishing Exploration – Motor Strip Dominance 1)Which hand do you write with? 2)Which hand holds scissors? 3)Which hand holds a hammer? 4)Which arm goes first into a jacket? 5)Which arm goes into the loop of a backpack/book bag first? 6)Which hand is on top when you clap? 7)Which hand deals out cards? 8)Which foot kicks a ball?

23 Tom Cruise David Archuleta & & Kasey Kahne

24 © West Educational Publishing In 1998, Governor Zell Miller of Georgia made sure every baby born in his state received an audiotape with classical music on it. A number of studies have show the positive effects music can have on the brain and this was one attempt at applying some of these findings.

25 © West Educational Publishing THE MOZART EFFECT Study done at the University of California at Irvine. Researchers found that listening to Mozart prior to completing a spatial task improved spatial reasoning.

26 © West Educational Publishing SPLIT BRAIN -David McNeil of Chicago) -Left-Hemisphere seems to specialize in linguistic coding: Syntax & Grammar -Right-Hemisphere seems to specialize in imagery, which may be reflected through gestures. -During discourse, it’s common for split-brain patients to speak, pause, then gesture, then resume speaking again. -CONCLUSION: BOTH HEMISPHERES ARE INVOLVED IN LANGUAGE.

27 © West Educational Publishing SPLIT BRAIN – Story Problem Split-Brain Sam is blind-folded. With his LEFT hand, he picks up a bell. He feels it… He rings it…. He knows it’s a bell. Would he be able to SAY it is a bell?

28 © West Educational Publishing SPLIT BRAIN – Story Problem (Answer) Since he CAN HEAR it, since BOTH EARS hear the bell, both hemispheres also “hear” it, and the talking left-hemisphere would be able to say, “It’s a bell.” HOWEVER, if he just picked it up and did NOT ring it, Split-Brain Sam probably would NOT be able to verbalize that the object name is “bell.”
