Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






2. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






3. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






4. Oculomotor Nerve - moves eye pupil






5. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






6. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






7. Cumulative effects of repeated stimulation from a presynaptic neuron






8. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






9. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






10. If head is rotated - eye movements occur in the same direction






11. Hypothalamic-pituitary-adrenal axis -controls stress response






12. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






13. Affect multiple receptors; highly preferential to which type of receptor they affect






14. Made from within - natural






15. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






16. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






17. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






18. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






19. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






20. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






21. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






22. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

23. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






24. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






25. Expression of traits






26. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






27. The female reproductive cycle of mammals other than primates






28. Measure changes in the electrical resistance of the skin (sweat gland activity)






29. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






30. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






31. Most pervasive excitatory neurotransmitter in the brain






32. Moving forward






33. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






34. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






35. Decreasing effects of a medication due to repeated administration






36. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






37. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






38. Opening in the iris; dilates and contracts allowing different levels of light in






39. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






40. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






41. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






42. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






43. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






44. Increasing effects/effectiveness of a medication due to repeated administration






45. Is everything anterior to the central sulcus






46. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






47. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






48. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






49. Is characteristic of indirect antagonist drugs






50. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*
