BASIC BRAIN FACTS.The average brain weights 3 lbsThe brain needs food/sleep/stimulationDevelopment is influenced by critical periodsThe brain is 90-95% of its full size by age 6The brain has a massive re-organization between birth and 1-year & 12-15The brain can repair itself (plasticity)The brain is always learning

Why study the brain?Treat diseases of the brain: Alzheimer's disease, schizophrenia, epilepsy, depression, learning disabilities, etc.To see what happens to a persons behavior when they are under the influence of drugsUnderstand the causes of violent behaviorChange someones IQ?The Cerebral cortexThe majority of the brain in humans1/10 thickCalled the Bark or Grey MatterContains 70% of Neurons in Central Nervous SystemCorticalization=Wrinkling of brain increases its size 2 Hemispheres Left Brain Focus on detailsInterprets/recognizes languageAnalyzes and evaluates factsTimeSequencing

Right Brain Processes images/visual patternsLanguage through context(body language/tone of voice)Recognizes places, faces & patternsTwo hemispheres connected byThe corpus callosum

Deep Inside the BrainThe Limbic SystemHippocampusThalamusAmygdalaHypothalamus

Language Center of the brain..Wernicke= Language Center

Broca=Speech Center

Wernicke

Disorders of Language..Aphasia= Partial or total loss of ability to articulate ideasAgnosia= Inability to identify objectsFacial Agnosia(Prosopagnosia)= Inability to recognize faces

Life sustaining brain structures

Medulla=breathing, swallowing, digestion, heartbeatPons=sleep & arrousalReticular Formation= arousal, attention, reflexesCerebellum= balance, coordinated movement
