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. 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






2. Skin senses that register the sensations of pressure - warmth and cold






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






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






5. 'little net'






6. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






7. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






8. Abducens Nerve - moves eye






9. 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)






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






11. 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






12. Is characteristic of indirect antagonists






13. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






14. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






15. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






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






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






19. Include tolerance (possible withdrawal) and sensitivity






20. 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






21. Is used to treat Parkinson'S Disease






22. Norepinephrine and serotonin






23. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






24. Regulates body temperature






25. Optic Nerve - sight






26. 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






27. 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






28. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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






31. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






32. Some brain communications are with the same side of the body






33. Is increased in its production by training/experience and therefore - associated with memory






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






35. Transparent substance between lens and retina






36. Expression of traits






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






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






39. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






40. Trigerminal Nerve - face sensation






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






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






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






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






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






46. 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

47. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

48. 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






49. 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)






50. 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
