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






2. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






3. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






4. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






5. Oculomotor Nerve - moves eye pupil






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






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






8. The maintenance of water balance in the body






9. 'Roof'






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






11. Vagus Nerve - heart rate and digestion






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






13. Trigerminal Nerve - face sensation






14. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






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






17. The female reproductive cycle of mammals other than primates






18. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






19. Sign






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






21. 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






22. 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






23. Pass the easiest through the blood-brain barrier






24. 'little brain'






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






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






27. 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






28. Hypoglossal Nerve - moves the tongue






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






30. Transparent substance between lens and retina






31. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






32. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






34. Glossopharyngeal Nerve - taste swallow






35. 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)






36. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






37. Midbrain - medulla and the pons






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






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






40. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






42. Olfactory Nerve - smell






43. Adenine - Guanine - Thymine - Cytosine






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






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






46. Symptom of narcolepsy - irresistible urge to






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






48. 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)






49. Supernormal






50. Colored part of the eye
