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. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






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






4. Regulates body temperature






5. Cumulative effects of repeated stimulation from a presynaptic neuron






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






7. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






8. Supernormal






9. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






10. Synchronized EEG activity during its deeper stages






11. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






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






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






14. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






15. Sleepwalking - sleep talking






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






17. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






18. 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






19. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






21. Sleep tests (i.e. to diagnosis sleep apnea)






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






23. 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)






24. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

25. Most pervasive excitatory neurotransmitter in the brain






26. 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






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






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






29. Opening in the iris; dilates and contracts allowing different levels of light in






30. 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)






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






32. Sign






33. Includes the tectum and tegmentum






34. Abducens Nerve - moves eye






35. Receive incoming sensory information or send out motor impulse commands






36. The maintenance of water balance in the body






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






38. 'Roof'






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






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






41. Hypothalamic-pituitary-adrenal axis -controls stress response






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






43. Glossopharyngeal Nerve - taste swallow






44. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






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






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






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






49. Norepinephrine and serotonin






50. Optic Nerve - sight
