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. Combines input from diverse brain regions; receives sensory information/sends motor impulses






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






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






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






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






6. 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






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






8. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






9. Regulates body temperature






10. Is found between the dura mater and arachnoid mater meninges






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






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






13. 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)






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






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






16. 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






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






18. 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)






19. Absolute; relative






20. 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)






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






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






23. Is a peptide neurotransmitter and a natural painkiller and antianxiety






24. Found in the hypothalamus - function to maintain the water balance in the body






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






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






27. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






28. 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






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






30. Audition: protrusions on top of midbrain; part of auditory system






31. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






32. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






33. Moving forward






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






35. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






36. Trigerminal Nerve - face sensation






37. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






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






39. 'covering'






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






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






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






43. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






44. 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






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






46. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

47. Hypoglossal Nerve - moves the tongue






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






49. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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