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. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






2. Synchronized EEG activity during its deeper stages






3. Produce drowsiness and sleepiness






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






5. Sleepwalking - sleep talking






6. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






7. Norepinephrine and serotonin






8. Moving forward






9. The increase in REM sleep seen after a period of REM sleep deprivation






10. A single - unfertilized cell created during conception; the combined egg + sperm






11. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






12. Some brain communications are with the same side of the body






13. Caudate nucleus and putamen






14. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






16. In the CNS - is an amino acid that stabilizes neural activity






17. 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






18. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






19. Includes the tectum and tegmentum






20. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






21. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






22. Decreasing effects of a medication due to repeated administration






23. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






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






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






27. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






28. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






29. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






30. 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






31. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






32. Maintains balance/posture and coordinates body movements






33. Pass the easiest through the blood-brain barrier






34. 'covering'






35. 'little brain'






36. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






37. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






38. Abducens Nerve - moves eye






39. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






40. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






41. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






42. Precursor to the catecholamine neurotransmitters (DA + NE)






43. Tremors - rigidity of limbs - poor balance and difficulty initiating movements


44. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






45. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






46. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






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






48. Is used to treat Parkinson'S Disease






49. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






50. Audition: protrusions on top of midbrain; part of auditory system
