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






2. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






3. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






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






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






6. An ovary or teste






7. An area that combines input from diverse brain regions






8. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






9. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






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






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






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






14. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






15. Includes the tectum and tegmentum






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






17. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






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






19. Regulates body temperature






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






21. 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)






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






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






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






25. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






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






27. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






28. Pass the easiest through the blood-brain barrier






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






30. The viscous substance between cornea and lens






31. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






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






33. Absolute; relative






34. 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)






35. 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






36. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






37. The visual image of the world on the retina






38. Trigerminal Nerve - face sensation






39. Controls sexual activity






40. 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






41. Hormones that reduce pain






42. The maintenance of water balance in the body






43. 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)






44. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






45. 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






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






47. Facial Nerve - moves face and salivates






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






49. 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






50. 'Roof'
