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






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






3. Is characteristic of indirect antagonists






4. Has neurons for reflexes






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






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






7. 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)






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






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






10. Norepinephrine and serotonin






11. The maintenance of water balance in the body






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






13. 'covering'






14. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






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






16. 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)






17. 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






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






19. Transparent substance between lens and retina






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






21. Is characteristic of indirect antagonist drugs






22. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






23. Abducens Nerve - moves eye






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






25. Hypoglossal Nerve - moves the tongue






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






27. 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

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






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






30. Found in the ventricles and spinal canal






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






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






33. Is used as an anaesthetic for children and animals but causes psychosis in adults






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






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






36. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






37. Are found in the diencephalon






38. Oculomotor Nerve - moves eye pupil






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






40. 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)






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






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






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






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






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






46. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






47. Sleepwalking - sleep talking






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






49. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






50. 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
