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. Supernormal






2. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






3. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






5. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






6. Vagus Nerve - heart rate and digestion






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






8. Controls sexual activity






9. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






10. Contains delta activity - stages III and IV






11. 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






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






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






14. Moving forward






15. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






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






17. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






18. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






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






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






21. Pass the easiest through the blood-brain barrier






22. 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)






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






24. Precursor to the catecholamine neurotransmitters (DA + NE)






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






26. 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






27. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






28. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






29. 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






30. Adenine - Guanine - Thymine - Cytosine






31. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






33. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






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






35. Is found in the interior rostral temporal lobe - part of limbic system






36. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






37. The maintenance of water balance in the body






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






39. Maintains balance/posture and coordinates body movements






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






41. Also known as ABLATION - is any surgically induced brain lesion






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






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






44. 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






45. Is regulated by the hypothalamus






46. Optic Nerve - sight






47. Important to motor system






48. 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)






49. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






50. 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)
