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. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






3. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






4. Trochlear Nerve - moves eye






5. 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






6. 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






7. Pass the easiest through the blood-brain barrier






8. Expression of traits






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






10. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






11. Oculomotor Nerve - moves eye pupil






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






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. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






15. Symptom of narcolepsy - irresistible urge to






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






17. Is everything anterior to the central sulcus






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






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






20. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






21. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






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






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






25. Regulates body temperature






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






27. Midbrain - medulla and the pons






28. 'Roof'






29. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






30. Facial Nerve - moves face and salivates






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






32. Affect multiple receptors; highly preferential to which type of receptor they affect






33. Transparent substance between lens and retina






34. Combines input from diverse brain regions; receives sensory information/sends motor impulses






35. Moving forward






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






37. Controls sexual activity






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






39. Is regulated by the hypothalamus






40. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






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

42. 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)






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






44. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






45. Hypoglossal Nerve - moves the tongue






46. Olfactory Nerve - smell






47. 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)






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






49. 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






50. 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
