1 Our partner in learning…
The Brain 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 Data
CT 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
