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






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






3. Include tolerance (possible withdrawal) and sensitivity






4. Includes the tectum and tegmentum






5. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






6. Is regulated by the hypothalamus






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






8. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






9. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






10. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






11. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






12. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






14. Absolute; relative






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






16. Projects to ventral tegmental area






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






18. Transparent substance between lens and retina






19. The female reproductive cycle of mammals other than primates






20. An area that combines input from diverse brain regions






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






22. The increase in REM sleep seen after a period of REM sleep deprivation






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






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






25. Adenine - Guanine - Thymine - Cytosine






26. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






28. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






29. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






30. 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)






31. 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






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






33. Is a peptide neurotransmitter and a natural painkiller and antianxiety






34. Caudate nucleus and putamen






35. Pass the easiest through the blood-brain barrier






36. Facial Nerve - moves face and salivates






37. 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)






38. 'little net'






39. 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)






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






41. Moving forward






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






43. ...






44. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






46. Produce drowsiness and sleepiness






47. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






48. Olfactory Nerve - smell






49. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






50. Decreasing effects of a medication due to repeated administration
