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 characteristic of indirect antagonist drugs






2. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






4. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






5. 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






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






7. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






8. 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






9. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






10. 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)






11. Vision: protrusions on top of the midbrain; part of visual system






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






13. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






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






15. Self-dissolving






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






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






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






19. Holds the lens in place






20. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






21. Pass the easiest through the blood-brain barrier






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






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






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






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






26. Important to motor system






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






28. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






29. The viscous substance between cornea and lens






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






31. Hypoglossal Nerve - moves the tongue






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






33. Precursor to the catecholamine neurotransmitters (DA + NE)






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






35. Trigerminal Nerve - face sensation






36. 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






37. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






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






39. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






40. 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






41. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






42. Is regulated by the hypothalamus






43. 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






44. Contains delta activity - stages III and IV






45. 'little net'






46. 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)






47. 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)






48. 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






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






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