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. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






2. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

3. 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

4. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






5. Glossopharyngeal Nerve - taste swallow






6. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






7. 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






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






9. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






11. Sign






12. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






13. 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






14. Dorsal part of midbrain; includes the superior and inferior colliculi






15. Consummatory stimulus






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






17. Important to motor system






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






19. Controls sexual activity






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






21. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






23. Most pervasive excitatory neurotransmitter in the brain






24. Moving forward






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






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






27. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






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






29. An ovary or teste






30. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






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






33. Include tolerance (possible withdrawal) and sensitivity






34. There are 12 add more






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






36. 'covering'






37. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






38. Vision: protrusions on top of the midbrain; part of visual system






39. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






40. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






41. An area that combines input from diverse brain regions






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






43. 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)






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. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






46. 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






47. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






48. Produce drowsiness and sleepiness






49. Pass the easiest through the blood-brain barrier






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