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. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






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






3. Is characteristic of indirect antagonists






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






5. Colored part of the eye






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






7. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






8. Synchronized EEG activity during its deeper stages






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






10. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






11. 'little brain'






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






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






14. Mechanism whereby neurons make connections to new areas to change their connectivity






15. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






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






17. Is an oversensitivity to dopamine (D2)






18. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






19. Cumulative effects of repeated stimulation from a presynaptic neuron






20. Receive incoming sensory information or send out motor impulse commands






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






22. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






23. Is used to treat Parkinson'S Disease






24. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






25. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






27. Decreasing effects of a medication due to repeated administration






28. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






30. Are found in the diencephalon






31. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






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






33. Is everything anterior to the central sulcus






34. Projects to ventral tegmental area






35. 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






36. ...






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






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






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






40. Expression of traits






41. 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)






42. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






43. 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






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






45. Norepinephrine and serotonin






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






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






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






49. 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)






50. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)
