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






2. 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






3. Self-dissolving






4. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






5. Vagus Nerve - heart rate and digestion






6. 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)

7. Norepinephrine and serotonin






8. Cumulative effects of repeated stimulation from a presynaptic neuron






9. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






10. ...






11. Referred to as the satiety center; lesions lead to obesity and hyperphagia






12. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






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






14. The viscous substance between cornea and lens






15. Damage to this are causes clumsiness and loss of balance






16. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






17. Olfactory Nerve - smell






18. Most brain communications are with the opposite side of the body






19. Important to motor system






20. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






21. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






22. 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






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






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






25. Moving forward






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






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






28. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






29. 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






30. The maintenance of water balance in the body






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






32. Is characteristic of indirect antagonists






33. Expression of traits






34. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






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






37. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






38. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






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






40. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






41. Is a peptide neurotransmitter and a natural painkiller and antianxiety






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






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






44. Is characteristic of indirect antagonist drugs






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






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






47. Regulates body temperature






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






49. Trigerminal Nerve - face sensation






50. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential
