Our partner in learning…

2. Our Brain: Essence and Existence

3. “FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS.”

4. Phrenology

5. New Technologies Yield “Explosion” of DataCT
EEG
MRI
fMRI
PET

6. BASIC BRAIN FACTS……. The average brain weights 3 lbs
The brain needs food/sleep/stimulation
Development is influenced by critical periods
The brain is 90-95% of it’s full size by age 6
The brain has a massive re-organization between birth and 1-year & 12-15
The brain can repair itself (plasticity)
The brain is always learning

7. Why study the brain?
Treat diseases of the brain: Alzheimer's disease, schizophrenia, epilepsy, depression, learning disabilities, etc.
To see what happens to a person’s behavior when they are under the influence of drugs
Understand the causes of violent behavior
Change someone’s IQ?

8. The Cerebral cortex… The majority of the brain in humans 1/10” thick
Called the “Bark” or “Grey Matter”
Contains 70% of Neurons in Central Nervous System
Corticalization=Wrinkling of brain increases its size

9. 2 Hemispheres Left Brain Focus on details
Interprets/recognizes language
Analyzes and evaluates facts
Time
Sequencing
Right Brain
Processes images/visual patterns
Language through context(body language/tone of voice)
Recognizes places, faces & patterns

10. Two hemispheres connected by…
The corpus callosum

11. Corpus Callosum

12. The Lobes The Frontal Lobe The Parietal Lobe Temporal Lobe
Occipital Lobe

13. Cerebellum

14. Frontal Lobe Critical thinking Reasoning Analysis Planning
Social behavior
Insight
Judgment
Self-control

15. Phineas Gage

16. Anterior Cingulate Gyrus
Impulse control
Goal directed behavior
Amount of attention given to thought/behavior
Ability to focus
See the world from another perspective
Make decisions when in conflict

17. Deep Inside the Brain The Limbic System
Hippocampus
Thalamus
Amygdala
Hypothalamus

18. Language Center of the brain..
Wernicke= Language Center
Broca=
Speech
Center

19. Wernicke

20. Disorders of Language..
Aphasia= Partial or total loss of ability to articulate ideas
Agnosia= Inability to identify objects
Facial Agnosia(Prosopagnosia)= Inability to recognize faces

21. Life sustaining brain structures
Medulla=breathing,
swallowing, digestion, heartbeat
Pons=sleep & arrousal
Reticular Formation= arousal, attention, reflexes
Cerebellum= balance, coordinated movement
