PSYCH 330 1st Edition Exam #5 Study GuideLecture#9(March 30th)What are the steps to completing a motor goal? What systems are integrated in this process?Step 1: Identification; visual cortex gives you what you’re seeing, ventral stream identifies, dorsal stream tells you how to use itif you severe the dorsal you can’t grasp but can identifyif you severe the ventral stream you can identify but can’t graspStep 2: Planning; frontal lobe plans for motion, how do i respond? how do i accomplish that response?prefrontal plans>premotor sequences>motor cortex decides which muscles tous Step 3: Communicating; Cortex gives this message to the spinal cordlateral corticospinal goes away from the midline from the cortex to the spinal cord, is responsible for independent movement(hands limbs, etc), info crossesventral corticospinal information leaving goes straight down(dorsal info is goingin), is for balance and postureStep 4: Telephone; The lateral corticospinal crosses over to get to the motor neurons, the interneurons in the corticospinal pathway pass the message from the corticospinal pathway to motor neurons and motor neurons project to musclesStep 5: Details; once you’re touching the object you access: how hot/how heavy/is it painful/how much pressurereaching out depends on where YOU are in space(proprioception); need to know how much you have to move to get where you want to beStep 6: Pass it on; receptor cell info you just collected goes through the tracts, dorsal for touch, spinothalamic tract for pain/tempStep 7: Editing; basal ganglia alters how strong you grasp it, cerebellum makes adjustments Step 8: Let your brain know you have grasped it Vision>plan>cortex-neuronsassessment> these messages sent through tracts>structures in brain edit->tell brain it’s doneLecture#10(April 3rd)What are the types of learning? What are the differences between them? How do we learn and maintain what we learned?Learning is getting info and memory is retrieving or referencing that information later study learning from the bottom up>encodeprocessstoreThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.learning=synaptic formation, more synapses dedicated to something so they have more of an influence, more nodes/spines>complex memories take complex circuitryfactors that alter circuitry= stress lessens branches, estrogen produces more brnaches forgetting or pruning is a part of learning, prune to make room for the new2 types:implicit(nondeclarative)learned through classical conditioning, procedural, motor learning, this memory is affected when the basal ganglia is affected so when you have parkinsons explicit(declarative)you have conscious access to, amnesialoss of declarativeAnterograde amnesiacan’t form new memoriesmost famous H.M had epilepsy from overexcitation of temporal lobe, doctors removed his hippocampus and he had no more epilepsy but had anterograde amnesiaShort term memorynot for storage, lasts from a min to a sec, working memory usesthe short term and manipulates it but does not store itIntermediatebetween long. short lasts a dayLong term can last years; Once you encode it and loop it in short term memorymany times it becomes long term, to maintain it as long term you need to continuallyreference it and think about it otherwise it will fadeLecture #11(April 6th)How is REM sleep different from the other stages? What factors influence your sleep cycle? What are the benefits of sleep?Initial muscle relaxationstwitching of limbs, feels like you’re falling NonREMstages ½fast brain waves, low muscle activity, no eye movement stages 3.4 deep sleep, high amplitude but slow brain wavesREMbasically muscle paralysis,fast waves, rapid eye movements, brain is working muscles are notendogenous factorsbody telling us to sleepbiological clock exogenous factorsoutside>sunlightcircadian rhythmdaily sleep cycle, the SCN in the hypothalamus is the pacemaker for circadian
