| Question | Answer |
| four lobes of the brain | parietal lobe
frontal lobe
temporal lobe
occipital lobe |
| frontal lobe | front lobe
motor cortex
broca's area (LEFT ONLY) |
| motor cortex | in frontal lobe
planning, control, and execution of voluntary movements |
| broca's area | LEFT SIDE ONLY
muscles involved in producing speech |
| parietal lobe | somatosensory cortex |
| somatosensory cortex | skin senses (skin, pain, etc) |
| occipital lobe | visual cortex |
| visual cortex | what we see |
| temporal lobe | auditory cortex
wernicke's area (LEFT SIDE ONLY) |
| auditory cortex | what we hear
understanding second language |
| wernicke's area | LEFT SIDE ONLY
comprehension |
| corpus callosum | makes the brain act as a whole |
| split brain research | cutting the corpus callosum and seeing how two brains interact |
| twin studies | identical twins- same genes not same amount of copies
fraternal twins- same womb but genetically different |
| limbic system | midbrain
amygdala
hypothalamus
hippocampus |
| amygdala | midbrain (limbic system)
hottest aggressions and biggest fears |
| hypothalamus | midbrain (limbic system)
body maintenance (hunger, thirst, heat, etc) |
| hippocampus | midbrain(limbic system)
conscious memories |
| nervous system | CNS PNS
Brain Spinal Cord somatic autonomic
sympathetic parapsympathetic |
| cns | decision maker |
| pns | gathers and transmits the decisions |
| somatic | voluntary descions |
| autonomic | involuntary descions |
| sympathetic | stress response center |
| parasympathetic | balances body out after stress response |
| ssri | selective class of drugs to treat depressive disorder, anxiety disorder, and other psychological disorders |
| reuptake | process when neurotransmitters are shot from synapse back up into terminal buttons |
| acetylcholine | forms new memories
low levels = alzhiemers |
| noraphinphrine | stress response
high levels- heart rate increase |
| dopamine | pleasure and reward response
too much = schizophrencics
too little = parkinsons |
| seratonin | too little = depression |
| endorphins | elevates mood and decreases pain
too much = (opioids) addiction |
| left brain functions | broca's area
wernicke's area
logic, facts, details, patterns, reality based, words and lang |
| right brain functions | feeling, imagination, present and future, philosophy and religion, spatial perception, fantasy based |
| sensory neurons | detect physical and chemical changes |
| motor neurons | outgoing messages to the muscles |
| interneurons | intervene between sensory and muscle neurons
reflexes |
| thalamus | hindbrain
relay center
all senses relay through thalamus besides smell |
| mri | use magnetic field to measure density and location of brain material |
| eeg | look at brain waves in different stages on conscious |
| cat/ct | computerized axial technology |
| x-ray | focuses on structure of brain |
| pet | what areas of brain are most active during a task |
| fmri | brain structure and blood flow ties structure to brain activity during a specific task |
| dollar drop demonstration | I drop the dollar myself- faster brain initiating drop and catch messages and i know when to put out those messages
Someone else drops dollar-takes more time for the message to go through my eyes, to my CNS, to my motor cortex, then finally to my hand |
| plasticity | if one area of brain is damaged other areas will connect neurons to compensate for damaged area
- the younger you are the more plastic your brain is |
