327787378Excitatory Neurotransmittersincrease the likelihood of an Action Potential0
327787379Inhibitary Neurotransmittersdecrease the likelihood of an Action Potential1
327787380agonistmimics or intensifies action of NT2
327787381antagonistopposes or blocks action of NT3
327787382Acetylcholine (Ach)enables every muscle(v and inv) important for memory and learning alzheimers: loss of Ach neurons agonist: convulsions, heart attack antagonist: curare( poision dart frog) botulism4
327787383Dopamineenables voluntary movement pleasurable emotions from food, water, sex parkinson's: muscle ridigity, tremors, speech, flat affect, caused by destruction of DA neurons Schizophrenia: elevated DA (6x # of receptors), creates hallucinations and delusions agonists: most drugs of abuse, cocaine, THC, meth5
327787384Seratoninregulates sleep, eating, and mood lower for people with depression agonists: selective seratonin reuptake inhibitors (SSRI's) antagonists: sugar w/LSD6
327787385Norepinephrinecontrols alertness, arousal, and mood stimulates CNS agonists: adderall, meth, speed, cocaine7
327787386Substance Psends pain messages vomiting center of the brain contains high levels antagonists: capsaicin, medication used in chemo8
327787387GABA (Gamma Amino Butyric Acid)inhibitory NT involved in 40% of all synapses prevents over stimulation of NS, regulates anxiety agonists: benzodiazepines, alcohol antagonists: rat poision, strict 99
327787388Endorphinsalleviate pain produce pleasurable emotions resemble opiates in structure and function creates runner's high agonists: opiates, morphine, heroine, vicadin, oxycotton10
327787389EEGElectroencepha Logram -measures electrical activity in the brain -sleep studies -epilepsy11
327787390CT ScanComputerized technology -x-ray slices -reveal brain damage and tumors12
327787391PET ScanPositron Emission Tomography -radioactive glucose shows how tissues and organs are working -shows brain activity as glucose is exposed13
327787392MRIMagnetic Resonance Imaging -magnetic field and radio waves provide detailed pictures of brain structures14
327787393fMRIFunctional Magnetic Resonance Imaging -measures increased blood and oxygen use15
327787394Cerebral Lateralizationspecialization of function between the 2 hemispheres16
327787395Left BrainLogic, Math, Language, right side of body/visual field17
327787396Right BrainSpatial, nonverbal, emotional expression, music/art appreciation, left side of body/visual field18
327844989Strokeflow of blood blocked by a clot or ruptured vessel, kills brain tissue effects: speech problems, unilateral paralysis, loss of coordination19
327844992Aphasiathe loss or impairment of the ability to express or understand language (caused by stroke) broca's: can't speak wernickles's: can't understand20
327844994Concussionmomentary loss of conciousness, severe or repeated can lead to memory and attention deficits, slurred speech21
327844996Traumatic Brain Injurymajor blow to head, mild impairment to death, changes in mood and expression22
327844998Lacerationpuncture to skull, can have varying effects depending on location23
327845001Alzheimer's Diseaseloss of neurons in hippocampus24
327845004ALS- Lou Gehrig's Diseasedegeneration of motor neurons25
327845006Parkinson's Diseaseloss of dopamine producing cells26
327845008Cerebral Commissurotorysplit brain surgery27
327845010Tumor Removal Surgeryeffects depend on location28
327845012Hemispherectomiesremove a hemisphere (most successful in young patients)29
327845015Brain Plasticityability of the brain to adapt and reorganize itself 1. experience can sculpt features of the brain (strengthens connections) 2. healthy neurons can reorganize and compensate for damaged ones 3. plasticity declines with age30
327845017Sensationstimulation of sense receptors that produces a neural impulse (Transduction)31
327845020Perceptionselection, organization and interpretation of information into something meaningful32
327845022Psychophysicsstudy of how physical stimuli and translated into psychological experiments Gustav Fechner (1801-1887) pioneer of psychophysics33
327845024Stimulusenergy that produces a response in the sense organ varies in both type and interest34
327845027Thresholdsdividing points between energy levels of stimulus that do and don't have a detectable effect35
327845030Absolute Thresholdthe smallest amount of stimulus that must be presented tin order to be detected 50% of the time -sugar and water: 1 tsp sugar to 2 gallons water -a candle flam seen 30 ft on clear night36
327845032Just Noticeable Difference Thresholdthe smallest amount difference in the amount of stimulation that a specific sense can detect37
327845036Weber's Lawthe JND is a constant proportion of the intensity of an initial stimulus -weight 1/50 to 1/30 (disputed) saltiness 1/538
327845040Sensory AdaptionGradual decline in sensitivity to prolonged stimulation -nerve cells fire less frequently -allows us to notice threats of safety or changes in enviornment39
327845044Selective Attentionfocus our awareness to a limited aspect of experience -cocktail party effect40
327845047Change Blindnessa form of selective attention that fails to notice changes in aspects of the enviornment41
327845050Subliminal Perceptionmessages that occur outside our concious awareness- below the absolute threshold -priming may occur as a result of SP -overall has a limited and fleeting effect and has not been proven to actually influence behavior42
327845053Vision Processing Conceptsfeature detectors- cells respond to specific features: lines, edges, angles, movement -parallel processing: color, movemen, form and depth simultaneously43
327845057Color Visionhuman visual light spectrum 400 nm to 700 nm in the EMS44
327845060Trichromatic Theory of Color Visionretinas have 3 types of cones: red, green, blue-violet different wavelengths combine to form up to 7 millions colors45
327849429Color Blindnessmonochromatic: no color receptors (rare) di-chromatic: lack function of red or green cones (more common in males)46
327849430Opponent-Process Theory-3 pairs of opposing receptors: red/green, blue/yellow, black/white -after-imaging produce opponent colors following over-stimulation and fatigue47
327849431Phi Phenomenona series of still images in sucession allows us to perceive motion48
