psych unit 1 pt 2
| Question | Answer |
|---|---|
| biological psychology | individuals who study the links between our genetic, neural, hormonal, and psychological processes |
| biopsychological approach | integrated approach that incorporates biological,psychological, and social-cultural levels of analysis |
| Levels of analysis | differing complementary views analyzing any given phenomenon |
| Neuroplasticity | brain is most flexible and can learn something new when your YOUNGER |
| Lesion | Tissue destruction -head injury, stroke - natural -lobotomy (violent individuals) - experiment |
| EEG | recording of the waves of electrical activity sweeping across the brains surface - used for epilepsy and sleep disorders |
| MEG | technique that measures magnetic fields from the brains natural activity |
| CT scan | series of X-ray photographs that represent of a slice of the brains structure |
| PET | detects brain activity that displays where a radioactive form of glucose goes |
| MRI | magnetic fields and radio waves to produce computer generated images of soft tissue (show brain anatomy) |
| fMRI | revealing blood flow and brain activity. show brain function as well as structure |
| LH | language |
| RH | recognizing human faces |
| Amygdala | emotion |
| Hippocampus | conscious memory |
| Hindbrain | bottom of brain, brain stem + cerebellum |
| Midbrain | middle of the brain, connects the other two regions |
| Forebrain | Top of the brain, visible folds and wrinkles (cerebral cortex) |
| Brainstem | beginning where the spinal cord swells as it enters the skull, maintain basic survival (part of the hindbrain) |
| Medulla | controls heartbeat and breathing (medulla oblongota) |
| Pons | structure in brainstem, regulates sleep and arousal, balance and spatial orientation |
| thalamus | sensory control center, directs messages and transmits replies (Atlanta airport) |
| Reticular formation | controlling arousal - key brain areas for waking you up |
| cerebellum | "little brain", coordinating movement output and balance (riding a bike, Simone Biles) |
| pituitary gland | MASTER gland |
| hippocampus | long-term memories (declarative memories/facts) |
| H.M. | case study, hippocampus removed, lost long term memories |
| location of function | certain areas of the brain are related to specific functions |
| cerebral cortex | most complex structure of the brain, divided into 4 lobes across two hemispheres |
| frontal lobe | front of the head, personality, making plans |
| parietal lobe | sensory input (touch, fluffy, soft, hard) |
| occipital lobe | visual fields |
| temporal lobes | auditory areas |
| motor cortex | controls voluntary movements (fingers, hands, mouth, and face) |
| somatosensory cortex | makes you aware of the sensation, registers and processes body touch and movement sensations |
| brocas area | speech (lips) |
| wenicks area | language comprehension |
| hemispherectomy | removal of one whole hemisphere of the brain |
| corpus callosum | neural fibers connecting the two brain hemispheres and carry messages between them |
| split brain | surgery that separates the brains two hemispheres |
| left hemisphere controls... | right side of body, language |
| right hemisphere controls... | left side of body, visuals |
| cognitive neuroscience | study of the brain activity linked with cognition |
| dual processing | information is often simultaneously processes on separate conscious and unconscious tracks (low road)(high road) |
| alpha waves | slow brain waves (relaxed) |
| Delta waves | large slow brain waves (deep sleep) |
| NREM sleep | Non rapid eye movement sleep |
| Hypnagogic sensations | feeling of falling or floating (jerking) |
| REM sleep | rapid eye movement sleep -dreams occour -paralyzed |
| Memory consolidation theory | helps strengthen and stabilize memories |
| restoration theory | brain to repair and restore itself |
| insomnia | problems falling and staying asleep |
| narcolepsy | uncontrollable sleep attacks |
| sleep apnea | cessations of breathing and repeated momentary awakenings during sleep -snoring -stop breathing |
| REM sleep behavior disorder | normal REM paralysis does not occur |
| REM Rebound | REM sleep to increase following REM sleep deprivation |
