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. Self-dissolving






2. 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






3. An ovary or teste






4. Contains delta activity - stages III and IV






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. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






7. Optic Nerve - sight






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






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






10. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






11. The maintenance of water balance in the body






12. Is used to treat Parkinson'S Disease






13. Is everything anterior to the central sulcus






14. 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






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






16. 'little brain'






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






18. 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)






19. Emotional perception and expression (particularly fearful emotions and detection of threat)






20. 'covering'






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






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






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






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






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






26. Sign






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






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






29. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






30. Include tolerance (possible withdrawal) and sensitivity






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






32. Supernormal






33. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






34. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






35. Hormones that reduce pain






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






37. Maintains balance/posture and coordinates body movements






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






39. Abducens Nerve - moves eye






40. Includes the tectum and tegmentum






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






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






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






44. 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

45. 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)






46. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






47. If head is rotated - eye movements occur in the same direction






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






49. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






50. Is found in the interior rostral temporal lobe - part of limbic system
