25
how information is transmitted in neuron
action potentials (electrical impulses) travel along axon and reach end (terminal button( which then send chemical messengers into synaptic cleft
26
neurotransmitters
chemicals that crosses synaptic cleft to transmit impulses from one neuron to the next
27
glial cells
recently learned that they play active roles in neural activity
28
major neurotransmitters
norepinephrine, serotonin, dopamine, GABA, glutamate
29
excitatory neurotransmitters
increase the likely hood that connecting neuron will fire (activate)
30
inhibitory neurotransmitters
decrease the likely hood that connecting neuron will fire (inactivate)
31
the brain is made up of
brain stem and forebrain
32
brain stem
-most essential automatic functions (breathing, sleeping, moving) -made up of hindbrain, midbrain, thalamus, and hypothalamus
33
hindbrain
made up of medulla, pons and cerebellum -regulates automatic activity like breathing, HR, and digestion
34
midbrain
coordinates movement with sensory input and has parts of RAS
35
reticular activating system
contributes to process of arousal and tension (ex: awake and asleep)
36
thalamus and hypothalamus
regulate behavior and emotion, serve as relay between forebrain and lower areas of brainstrem
37
limbic system
-hippocampus, cingulate gyrus, septum, amygdala -helps regulate emotional experiences and expressions -ability to learn and control impulses -basic drives of sex, aggression, hunger and thirst
38
basal ganglia
- at base of forebrain and includes caudate nucleus -controls motor activity
39
cerebral cortex
-largest part of forebrain (80% of neurons) -allows for us to plan, reason and create -divided into 2 hemispheres that are different
40
left hemisphere
verbal and cognitive processes
41
right hemisphere
better at perceiving the world around us and creating images
42
4 lobes
temporal, parietal, occipital and frontal
43
temporal lobe
recognizing sights and sounds long term memory storage
44
parietal lobe
recognizing sensations of touch and monitoring body positioning
45
occipital lobe
integrating and making sense of visual inputs
46
frontal lobe
-prefrontal cortex: higher cognitive function (thinking, reasoning and long term memory)
47
what part of the brain synthesizes all information received from other parts of brain and decides how to respond
prefrontal cortex
48
somatic nervous system
controls muscles
49
2 divisions of autonomic nervous system
sympathetic and parasympathetic
50
autonomic nervous sytem
regulates cardiovascular and endocrine systems, aids in digestion and regulates body temp
51
endocrine system
composed of glands that produce hormones (chemical messenger)
52
adrenal glands produce
-epinephrine; in response to stress -salt regulating hormones
53
thyroid gland produces
thyroxine which regulates energy metabolism and growth
54
sympathetic nervous system
-mobilizes body during times of stress (fight or flight) - increase HR and respiration, stimulate adrenal glands
55
parasympathetic nervous system
-calm/balance to sympathetic -facilitates storage of energy by helping digestion
56
agonists
chemical substance that increases the activity of a neurotransmitter by imitating its effects
57
antagonists
chemical substance that decreases or blocks the effects of a neurotransmitter
58
inverse agonists
chemical substance that produces effects opposite of a particular neurotransmitter
59
reuptake
action by which a neurotransmitter is quickly drawn back into the discharging neuron after being released into the synaptic cleft
60
monoamines
norepinephering, serotonin and dopamins
61
amino acid neurotransmitters
gamma-animobutyric acid (GABA) and glutamate
62
glutamate
excitatory transmitter that turns on many neurons
63
GABA
inhibitory neurotransmitter that regulates/stops transmission of action potentials and info
64
best known effect of GABA
to reduce anxiety
65
benzodiazepines
make it easier for GABA molecules to attach themselves to neuron receptors which leads to becoming more calm (minor tranquilizer)
66
GABA system reduces levels of
anxiety, muscle movement, anger, aggression and positive emotional states such as eager anticipation and pleasure
67
serotonin (5HT)
-6 major circuits in midbrain -regulates behavior, moods and thought processes
68
extremely low levels of serotonin
less inhibition and instability, impulsivity and overreaction
69
low levels of serotonin
aggression, suicide, impulsive overeating and excessive sexual behavior
70
norepinephrine
stimulates alpha and beta adrenergic receptors, regulates certain behavioral tendencies (panic) and is not directly related to psychological disorder
71
beta blockers
block beta adrenergic receptors so that response to surge of norepinerpherine is reduced which keeps BP and HR lower
72
dopamine
-often associated with schizophrenia and addiction, and depression and ADHD
73
L-dopa
dopamine circuit that is an agonist to dopamine -circuit that regulates ability to move in coordinated way -can be used to treat parkinsons and tremor diseases
74
initiating factors
the reasons why the problem develops
75
maintaining factors
the reasons why the problems persists
76
exposure and response prevention (using CBT)
found that brain circuits had been changed on patients that had been treated by CBT
77
study on psychosocial factors and levels of neurotransmitters
-group 1: monkeys living in cage with control (access to toys) -group 2: monkeys living in cage with no control (only get toys when group 1 played with the toys) -both groups given benzodiazepine (extreme anxiety) -group 2: panicked and severe anxiety group 1: did not seem anxious but were angry and aggressive -conclusion: chemical substance had different effects depending on psychological and environmental histories
78
study on psychosocial effect on brain structure and function
the nervous system of rats raised in rich environment that required they do a lot of learning and motor behavior developed differently than rats that were couch potatoes -rich environment rats had more connections between nerve cells in cerebellum and grew more dendrites
79
cognitive science
examines how humans acquire, process, store and retrieve information
80
complex conditional processing of information as well as emotional processing is involved when
conditioning occurs
81
learned helplessness
Seligmans theory that people become anxious and depressed when they make an attribution that they have no control over the stress in their lives (whether or not they do in reality)
82
learned optimism
if people faced with considerable stress and difficulty display an optimistic, upbeat attitude, they are likely to function better psychologically and physically
83
those who had positive views about themselves and aging lived
7.5 years longer
84
modeling/ observational learning
learning through observation and imitation of the behavior of other individuals and consequences of that behavior
85
prepared learning
we have become highly prepared for learning about certain types of objects or situations over the corse of evolution because the knowledge contributes to the survival of the species
86
implicit memory
condition of memory in which a person cannot recall past events despite acting in response to them
87
explicit memory
conscious memory for events
88
fight or flight response
biological reaction to alarming stressors that activate the body's resources
89
physiology of fear
-blood vessels constrict to raise arterial pressure and decrease flow to extremities -excess blood redirected to muscles where it is available to vital organs -breathing increases to bring in more O2 to give to brain to stimulate cognitive processes and sensory functions to make more alert and think quickly -glucose mobilized from liver to energize muscle and organs
90
emotion
patter of action elicited by an external events and a feeling state accompanied by a characteristic physiological response
91
mood
persustent period of affect or emotionality
92
affect
conscious, subjective aspect of an emotion that accompanies an action at a given time
93
circumplex model
describes different emotions as points in a 2 dimensional space of valence and arousal
94
valence
goodness/badness of a situaiton, often associated with "affect"
95
3 components of emotion
behavior, physiology, cognition
96
emotion scientists conc on behavior
think that basic patterns of emotion differ from one another in fundamental ways (ex: anger differs from sadness), think emotion is way of communicating with each other
97
emotion scientists conc on physiology
view emotion as a brain function, areas of brain are associated with emotional expression and are more ancient/primitive, neurobiological connections between emotional centers and eye/ear
98
emotion scientists conc on cognitive aspects
Lazarus thought that changes in a persons environment are analyzed in terms of their potential impact on that person and the type of analysis you make determines the emotion you perceive (thinking and feeling cannot be separated) but others disagreed with him saying cognitive and emotional systems interact and overlap
99
hearts efficiency to pump blood throughout the body decreases during times of
anger (but not stress or exercise)
100
fright disorders
exaggerates startle responses and other observable fear and anxiety reactions
101
susto
various anxiety symptoms (insomnia, irritability, phobias and marked somatic symptoms) that are attributed to the individual believing they are object of black magic or witchcraft
102
Haitian voodoo death
sentence of death by a medicine man can create intolerable autonomic arousal in someone who has no ability to cope (has no social support), eventually leads to damage of internal organs and death
103
insect or small animal phobias more likely in
females
104
social phobias affect men and women
equally
105
the more social relations and interactions you have
the longer you are likely to live
