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. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






2. Adenine - Guanine - Thymine - Cytosine






3. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






4. Two different presynaptic neurons/inputs to a post-synaptic cell






5. Is regulated by the hypothalamus






6. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






7. 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






8. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






10. Viscous substance between cornea and lens; transparent substance between lens and retina






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






12. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






13. Is characteristic of indirect antagonists






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






15. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






17. Symptom of narcolepsy - irresistible urge to






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






19. Are found in the diencephalon






20. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






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






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






23. 'little brain'






24. 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






25. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






26. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






27. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






28. The female reproductive cycle of mammals other than primates






29. Optic Nerve - sight






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






32. 'Roof'






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






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






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






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






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






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






39. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






41. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






42. Glossopharyngeal Nerve - taste swallow






43. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






44. Is found in the interior rostral temporal lobe - part of limbic system






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






46. Regulates body temperature






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






48. Vagus Nerve - heart rate and digestion






49. 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






50. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level
