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






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






3. An area that combines input from diverse brain regions






4. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






5. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






8. Holds the lens in place






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






10. 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

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






12. Midbrain - medulla and the pons






13. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






14. Vagus Nerve - heart rate and digestion






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






16. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






17. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






18. Made from within - natural






19. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






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






22. Oculomotor Nerve - moves eye pupil






23. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






24. ...






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






26. 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






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






28. 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






29. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






30. Found in the ventricles and spinal canal






31. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






32. Contains delta activity - stages III and IV






33. 'Roof'






34. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






35. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






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






38. 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






39. Facial Nerve - moves face and salivates






40. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






41. 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






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






43. Is regulated by the hypothalamus






44. Is characteristic of indirect antagonists






45. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






46. Pass the easiest through the blood-brain barrier






47. 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






48. 'little brain'






49. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






50. Is used as an anaesthetic for children and animals but causes psychosis in adults
