philosophy 0 His challenge bridge physiology and philosophy 0 His answer psychology o Bringing in empirical scienti c questions to answer deep philosophical questions 0 Maybe mindbody are together 2 ways of thinking emerged from people like him 0 Dualism interaction between bodymind o Monoism the 2 are basically one no difference between brain and behavior 0 No matter which school of thought there is a basically blending between brain and behavior Wundt idea William James physiologistfather of American text book on psychology 1st chapter on how the brain works Methodology questions empiricism physiology Big questions 0 Do we have a soul 0 Who are we 0 What is the purpose of knowledge 0 Where does consciousness come from Genetics or environment The more emotionalcognitive side of life is harder to predict Appears to come from both environment and gene pool complex interplay that comes together to produce behavior 0 Why is it hard to gather knowedge What is going through someone s mind when they inject heroin Long term v shortterm rewardsconsequences AgtBgtConly a fool learns from experience if your smart you will let some one else do it for you if really smart you use foresight Sperry s questions in introtopsych 1 What is consciousness 2 Where does it come from Necessary for wisdom usefulpurposeful outcomes Consciousness a method of gathering info about the world making sense of what s happenedthe interpretation to guide your behaviorwho I am in that world If a bird is not exposed to song of their species they never actually learn it geneticsenvironment 3 Where is all this information located Where is it storedprocessed lThe brain lAll things being equal 2 areas of great interest to us 1 Front part of brain understandsinterpretstakes up info makes sense of itljstuffs it into temporal lobe to use again and again learning is solving a problem once so you don t have to do it again 4 How do people engage in adaptive processes How do some people make it and others don39t Puente39s question Norma Sperry Why do you think Roger got the Nobel Prize 0 Chemo nity theory brain is much more hardwired than we thought 0 Roger said we are 95 hardwired but other 5 is more important 0 What he discovered with splitbrain was that even in humans it was pretty hardwired Did you ever meet any of splitbrain patients 0 CLASS 3 827 Neuron basic building block LCD see picture SOMA Structure Nucleus containing ribosomes Mitochondria Golgi bodies Similar to regular biological cell Dendrite what receives info data receptor source of data 0 Dendrite terminals openings allow for admission of chemicals 0 Axon where info goes out it s structure 0 White covering myelin sheath the myelin is NOT consistent has spaces Nodes of Ranvier tiny spaces in between the myelin Different types of Axons A B C A lots of myelin B middle myelin C bers very little myelin pain Axon Terminal little openings allow for discharge of chemicals OOOOOO Synaptic vesicles contain neurotransmitters chemicals that are there to be dischargedthese chemicals are discharged into the synapse space between axon terminal and dendrites These is how info is carried and what differentiates a neuron from other biological cells One neuron could actually effect many other neurons Sequential sort of 1 Dendriteljsomaljaxonljterminalneuron 2 Function of Neurons Interesting the more a drug matches the con gurement of the receptor the more it looks like a neurotransmitter the more addictive it is The spot between the SOMA and the action where real action actionpotential happens 0 Loss of myelin slows down actionpotential 0 When we are going down the action we don t go straight forward we jump o Saltatory saltare salutatory conduction jumping from node of ranvier to the next nrat end goes to synaptic vesiclesopen it up and releases into synapse if neuron transmitter is right t you have actionpotential o The chemicals Sodium and potassium Theres a little bit of both inside and outside membrane 0 When you get action potential there is a big change in the balance sodium 2530 40 o Resting potential no actionstarts at 70 goes up to 40 back down to 80 back up to 70 o The heart EKG the Brain EEGa whole bunch of action potential 0 Either you have AP or you don t like a light switch quick and spontaneous 0 Difference between sodium and potassium 70 mV Only 2 things can happen in the synapse2 Options for a neurotransmitter having an effect excitation or inhibition a binary system But you can quotExcitequot neurons associated with negativity Drugs excite or inhibit not this simple Ex alcohol inhibits inhibitionljaggression could come out 100 billion x 2 the number of permutations possible in the brain How do you get behavior out of all these permutations NOT TRUE that you only use 10 of your brain at any one point you use all of itbut certain parts are more active at certain points We want to discover patterns when you are doing wellpatterns when you are not The brain is like a gestalt the whole is much more than the sum of the parts the gestalt supersedes the knowledge of those individual cells Its not the individual cells that count it39s the pattern in the whole Class 4 91 HOW DO GET INFO FROM OUTSIDE AND WHAT DO I DO WITH IT John Locke39s idea Puente thinks false tabula rasablank slate when you are born all knowledge comes from outside How do we become educated By gathering data from the outside The better info you put in better knowledge you have How do you put it in What is the raw data going in sensation Why do to a concert on drugs perception Sensation vs perception SENSATION Sensesgestation auditory visual tactile kinesthetic pain temperature ESP there s about 10 sensesm0re than just 5 Each sense into 3 parts outside processor transducer conductor nerve Vision For many of us the most important one 1 way to get into the brain easily through the eye sockets Rods bw and cones Color in the retina Cornearetina gather data Optic nerve crosses over conduceraseptical lobethe processor See diagram Headng We can only get a portion of the decibels The ear is shaped a certain way to funnel info 0 Ear transforms sounds into mechanical movements sends info to auditory nerve then auditory cortex 0 Balance is here vestibular systemcochlea Touch 0 Almost all touch is assoc w mechanical input 0 Where are there a lot of nerve endings Where do you want to be touched Facegenitalshands o Nerve endings are mechanical Gestation Receptors in tongue stimulus chemicals 0 Tip of tonguesweet sidessour o Saltytop Olfactory 0 Chemicals oating in air hang on to hairs in your nose 0 Not tasting is common in dementia inability to smell is often rst to go Pain 0 Pain receptors are located in lots of speci c areas 0 It s about the way that carry the receptors C bers Temperature 0 Assoc with receptors on skin some parts more sensitive than others Kinesthetic Combo of info from multiple senses Sense of places for parts of the body One of most dif cult to understand When people lose knowledge of a limb deep inside brain Phantom limb mechanical with way nerve was cut You can have sensory info without any sensory info occurring Sensory deprivation will produce sensory illusions you can have info occurring without info coming in CLASS 5 SEE NOTEBOOK CLASS 6 98 530630 tonight 3 points join and register with thepracticeinstitutecom Rule of thumb the lower the brain the harder it is to train Any system is made up of interconnected structures that must function simultaneously Middle part is more sophisticated than lower part Medulla A Picture 1 0 Medulla A breathing heartbeat things that keep you alive 0 Fiber cross over 10 of motor bers DON T cross over extra pyramidalfine motor stuff but 90 do pyramidal does quotgrossquot functions We don t really know why 10 doesn t If you go into coma and this section is damaged you are done Pons 0 More info regarding life activities 0 Beginning of place that turns you onoff Light function diurnal animal humans awake during day you could train it but not completely Midbrain Where a lot of motor functions really get going Nigra 0 The real center for diurnalnocturnal patterns a rat has a very different pattern than us The Reticular Formation 0 Within the medulla pons midbrain 0 23 part of the lower brain stem this is what develops the basic consciousness of which there are 3 levels awake asleep in deep sleep or REM sleep 0 Regulates these 3 states of consciousness the inner core of what makes things happen 0 If you go into a coma a good likelihood you are messing with the RFan inefficient working RF When you overdose the reticular formation stops working Central thing that keeps you most alive 0 When you drink you keep going down the latter when you are passed outrf is sputtering The Cerebellum Historically we thought it was all about motor functionsturns out it is much more complex with a lot to do with cognition Feeds into the substantion nigra name we are still learning about it don t know as much as we thought The Diencephalon picture 2 2nCI section not as simple geographically as the rst part a series of systems made up of 4 different structures made of nerve bers Basal ganglia1functionthe motor system Caudate Putamen Blobus Pallidos quotneed all simultaneously Parkinson sa lack of dopamine in Caudate The Limbic System Some people would call this the emotional system Here we start to see some difference from nonhumans Septal areasex says yes or no to sex Hippocampusassociated with 1 primary functionthe development of memory not great place for the storage of it but good for getting memories 0 Alcoholics impair ability to learn new infovitamin de ciency o Bypass surgeryljsome strokes in the hippocampus not dissimilar to those of alcoholics o The more you rehearse a thought the less likely it is for you to get rid of it o Ours can store way more info than animals Amygdala associated with aggression a problem with it is deregulating Hypothalamus 0 Tiny structure that controls temperature regulation hunger thirst and to a degree sex 0 Deals with all of your biological motivation if you don t have this intact hasta la vista Series of interrelated structures Polydipsia Why is your grandma wearing a sweater in the summer If you get rid of some portions of it you get obese OOOO Cerebral Cortex This is the part that really sets you apart as human The last part to evolve most sophisticated Also last part to grow about 18 19starts dying around 19 If you use your brain correctly regularly you become more wise you need fewer cells to produce better results The Corpus Callosum AnteriorPosterior Commisures coordination of activity o If not connecteddisjointed individual Leftogic reasoning verbal right handed directed 0 Right hemispherevisual gestalt emotional the big picture o If not connected they are like two different individuals competing with each other 0 2 sides have 4 lobes each8 lobes total the lobes are swayed by either visualverbal side of things
