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. The female reproductive cycle of mammals other than primates






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






3. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






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






6. Absolute; relative






7. 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)






8. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






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






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






11. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






12. Pleasure center of the brain; discovered by Olds & Milner






13. All have similar molecular structure - so many 'dirty' medications






14. Is used as an anaesthetic for children and animals but causes psychosis in adults






15. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






17. Is characteristic of indirect antagonists






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






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






20. Vestibulocochlear Nerve - hearing and balance






21. Accessory Nerve - moves the head






22. 'little brain'






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






24. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)


25. 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


26. The visual image of the world on the retina






27. Expression of traits






28. 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






29. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






30. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






31. 'covering'






32. 'Roof'






33. Is regulated by the hypothalamus






34. Regulates body temperature






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






36. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






37. Adenine - Guanine - Thymine - Cytosine






38. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






39. 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






40. There are 12 add more






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






42. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






43. 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






44. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






45. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






47. Also known as ABLATION - is any surgically induced brain lesion






48. Is used to treat Parkinson'S Disease






49. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






50. Hormones that reduce pain
