Exam 1 Psychology
| Question | Answer |
|---|---|
| Relay station | Thalamus |
| Regulates physiological feedback systems(hunger, thirst, temperature, sexual behavior) | Hypothalamus |
| Connects sensory and emotional information(part of lambic system) | Amygdala |
| Memory | Hippocampus |
| Primary processing area | Cerebral cortex |
| Transfers info between the 2 cerebral hemispheres | Corpus callosum |
| Occipital Lobe | Vision |
| Temporal lobes | Hearing and language |
| Area on temporal lobe, primary function if speech/language comprehension | Wernicke’s area |
| Frontal lobes | Personality, thinking, motor cortex(executive functioning) |
| Area in frontal lobes, primary function is speech production | Brock’s area |
| Parietal lobes | Touch, temperature, pain, soma sensory cortex |
| Strip of frontal lobes that generates commands for movement | Motor cortex |
| Strip of parietal lobes that perceives touch(more sensitive areas of the body have larger assigned portions) | Somatosensory cortex |
| Controls pituitary gland, which controls endocrine glands in body l(pancreas, thyroid, etc.) | Hypothalamus |
| Controlled by right hemisphere; language, verbal skills, speech, reading and writing | Left hemisphere of brain |
| Controlled by left hemisphere; nonverbal, spatial, musical, visual recognition | Right hemisphere |
| Synaptic plasticity | The brains ability to crest and change the strength of synapses |
| Nature-nurture | How much of who we are is determined by hereditary vs. environmental influences |
| Social Psychology | study of social behavior & interactions |
| "just world" Hypothesis | The bias or assumption that people get what they deserve, or life is fair |
| Cells specialized for communication | Neurons |
| Cells that support, insulate, nourish, & regulate neurons | Glial cells |
| Dendrites | receive info from other neurons and carry info towards cell body |
| axon | sends info away from cell body to other neurons, muscles, or glands |
| myelin | fatty covering that insulates many axons |
| Type of message(graded potential) that make the neuron more likely to send a message | Excitatory graded potentials |
| Type of message(graded potential) that make the neuron less likely to send a message | Inhibitory graded potentials |
| When the action potential reaches the end of the axon, it releases___________ molecules, which carry the message to the next neuron | neurotransmitter |
| Space between end of axon on one neuron and dendrites of another | synapse/synaptic gap/synaptic cleft |
| NT molecules fit into_____ ____ on the dendrites of the next neuron | receptor sites |
| very short "resting period" after sending an action potential in which a neuron cannot send another action potential | refractory period |
| mental illness is often related to problems in how ________ communicate with one another | neurons |
| Agonists | mimic the effect of a NT |
| Antagonists | Block the effect of a NT |
| NT that is associated with movement, memory, alzheimer's disease, and nicotine | Acetylcholine |
| NT that is associated with sleep, learning, mood, depression, and the "fight or flight" reaction | Norepinephrine |
| NT that is associated with mood, depression(SSRIs), appetite, and sleep | Seratonin |
| NT that is associated with Movement, parkinson's(too little), Schizophrenia(too much) and motivation(reward/pleasure) | Dopamine |
| NT that is associated with Huntington's(too little), Epilepsy, Anxiety(too little) and is the main inhibitory NT | GABA |
| NT that is the main excitatory NT, strengthens connection between synapses, and is associated with neuron loss after stroke | Glutamate |
| NT that is associated with pain perception and opiate drugs | Endorphins |
| 2 major divisions of nervous system | CNS(brain and spinal chord), PNS(somatic nervous system--voluntary behavior, sensory and motor neurons) |
| 2 types of Autonomic Nervous system(mostly involuntary) | Sympathetic(increases arousal), parasympathetic(decreases arousal) |
| 3 major subdivisions of hindbrain | Medulla, Pons, Reticular formation(extends into midbrain), Cerebellum |
| Medulla(hindbrain) | controls vital functions |
| Pons(hindbrain) | connects brain and spinal chord |
| Cerebellum(hindbrain) | coordinates movement |
| major structures of midbrain | Substantia Nigra, Reticular Formation |
| Substantia Nigra(midbrain) | movement |
| Reticular Formation(midbrain) | sleep and arousal, attention(filtering of info) |
