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. Two different presynaptic neurons/inputs to a post-synaptic cell






2. An ovary or teste






3. Controls sexual activity






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






5. Is everything anterior to the central sulcus






6. 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






7. 'covering'






8. 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






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






10. Portion of a sensory field to which a cell responds






11. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






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






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






14. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






15. Accessory Nerve - moves the head






16. 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






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






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






19. Is used to treat Parkinson'S Disease






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






21. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






22. Facial Nerve - moves face and salivates






23. Hormones that reduce pain






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






25. Mechanism whereby neurons make connections to new areas to change their connectivity






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






27. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






28. All have similar molecular structure - so many 'dirty' medications






29. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






30. Norepinephrine and serotonin






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






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






33. Important to motor system






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






35. 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






36. 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)






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






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






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






40. Consummatory stimulus






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






42. Most brain communications are with the opposite side of the body






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






44. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






45. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






46. 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)






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






48. Vagus Nerve - heart rate and digestion






49. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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