Today’s Learning Objectives:
#5. I can explain one study related to localization of function in the brain.
Today’s Agenda:
Localization
HW:
CRA

2. Localization of Function

3. Definition
The assumption that specific functions are associated with specific areas of the brain

4. Animal experimentation Lesioning Post-mortem studies Case studies
Research
Research is based on:
Animal experimentation
Lesioning
Post-mortem studies
Case studies
Computer imaging

6. Phineas Gage RR worker injured by an explosion Frontal lobe damage
In particular, the ventromedial region on the left side at the underbelly of the frontal lobe
Was able to recover and function normally but his personality drastically changed

7. Paul Broca
1861: Discovered an area of the left frontal lobe involved with speech production, specifically “syntax”
It has been known as “Broca’s Area” ever since

8. Broca’s Area

9. Carl Wernicke
1874: Discovered an area in the left hemisphere crucial for language comprehension
Left posterior superior temporal gyrus
Would become known as Wernicke’s Area

10. Wernicke’s Area

11. So, what’s the difference???
To mean: "The dog needs to go out so I will take him for a walk.”
So, what’s the difference???
Broca’s aphasic patient might say:
“Walk dog.”
Wernicke’s aphasic patient might say:
“You know that smoodle pinkered and that I want to get him round and take care of him like you want before.”

12. Can we see it in action???
Transcranial Magnetic Stimulation (TMS) is a technique for temporarily disrupting the function of specific cortical regions. The technique is noninvasive and is not known to have residual effects.

13. Other Study: Gazzaniga

As you watch, take note of the following:
Method
AIM/Hypothesis
Procedure
Results
Implications (how does this relate to localization of brain function)

14. Using your Learning Outcomes Chart
What studies have you read about and/or discussed in class?
To which Learning Outcomes might those studies apply?
