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. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






2. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






3. 'covering'






4. Caudate nucleus and putamen






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






6. The increase in REM sleep seen after a period of REM sleep deprivation






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






8. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






9. 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)






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






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






12. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






13. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






14. Controls sexual activity






15. Glossopharyngeal Nerve - taste swallow






16. Found in the ventricles and spinal canal






17. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






18. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






19. Regulates body temperature






20. Dorsal part of midbrain; includes the superior and inferior colliculi






21. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






22. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






23. Pleasure center of the brain; discovered by Olds & Milner






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






25. Synchronized EEG activity during its deeper stages






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






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






28. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






29. Hormones that reduce pain






30. 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

31. The female reproductive cycle of mammals other than primates






32. Includes the tectum and tegmentum






33. 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)






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






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






36. Is used to treat Parkinson'S Disease






37. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






39. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






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






41. Include tolerance (possible withdrawal) and sensitivity






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






43. 'little net'






44. Olfactory Nerve - smell






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






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






47. Produce drowsiness and sleepiness






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






49. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






50. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important
