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. Is a peptide neurotransmitter and a natural painkiller and antianxiety






2. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






5. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






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






7. If head is rotated - eye movements occur in the same direction






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






9. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






10. Viscous substance between cornea and lens; transparent substance between lens and retina






11. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






12. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






15. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






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






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

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






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






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






21. Colored part of the eye






22. 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






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






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






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






26. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






27. Adenine - Guanine - Thymine - Cytosine






28. Maintains balance/posture and coordinates body movements






29. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






30. Sleepwalking - sleep talking






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






32. Trochlear Nerve - moves eye






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






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






35. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






36. 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)






37. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






38. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






40. Glossopharyngeal Nerve - taste swallow






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






42. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






43. Made from within - natural






44. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






45. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






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






48. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






50. 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
