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. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






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






3. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






5. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






6. Emotional perception and expression (particularly fearful emotions and detection of threat)






7. 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)

8. Midbrain - medulla and the pons






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






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






11. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






12. Sign






13. 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






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






15. Measure changes in the electrical resistance of the skin (sweat gland activity)






16. Projects to ventral tegmental area






17. Glossopharyngeal Nerve - taste swallow






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






19. 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






20. Symptom of narcolepsy - irresistible urge to






21. Trochlear Nerve - moves eye






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






23. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






25. 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

26. Oculomotor Nerve - moves eye pupil






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






28. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






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






31. Maintains balance/posture and coordinates body movements






32. Self-dissolving






33. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






34. There are 12 add more






35. Trigerminal Nerve - face sensation






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






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






38. Consummatory stimulus






39. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

40. Moving forward






41. Synchronized EEG activity during its deeper stages






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






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






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






45. Sleepwalking - sleep talking






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






47. Is everything anterior to the central sulcus






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






49. Is characteristic of indirect antagonist drugs






50. Cornea - aqueous humor - pupil - lens - vitreous humor - retina
