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






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






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






4. Controls sexual activity






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






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






7. 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






8. All have similar molecular structure - so many 'dirty' medications






9. Maintains balance/posture and coordinates body movements






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






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






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






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






14. Consummatory stimulus






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

16. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






17. Referred to as the satiety center; lesions lead to obesity and hyperphagia






18. Sleep tests (i.e. to diagnosis sleep apnea)






19. 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






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






21. Accessory Nerve - moves the head






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






23. Decreasing effects of a medication due to repeated administration






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






25. Is used to treat Parkinson'S Disease






26. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






27. Contains delta activity - stages III and IV






28. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






29. 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)






30. Found in the hypothalamus - function to maintain the water balance in the body






31. 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)






32. Norepinephrine and serotonin






33. An ovary or teste






34. Oculomotor Nerve - moves eye pupil






35. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






36. Has a calcium-related role and produces the hormone parathyroid






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






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






39. Glossopharyngeal Nerve - taste swallow






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






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






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






43. 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






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






45. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






46. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






47. 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)






48. 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






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






50. Damage to this are causes clumsiness and loss of balance
