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 defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






2. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






3. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






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






6. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






7. Found in the ventricles and spinal canal






8. Midbrain - medulla and the pons






9. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






11. Holds the lens in place






12. 'little net'






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






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






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






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






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






18. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






19. Regulates body temperature






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






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






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






23. 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






24. 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)






25. Absolute; relative






26. Norepinephrine and serotonin






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






28. Are found in the diencephalon






29. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






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






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






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






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






34. Audition: protrusions on top of midbrain; part of auditory system






35. Synchronized EEG activity during its deeper stages






36. Functions as both a hormone and a neurotransmitter in the brain






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






38. Is found between the dura mater and arachnoid mater meninges






39. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






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






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






43. The visual image of the world on the retina






44. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






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






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






47. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






48. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






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






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