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






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






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






4. Consummatory stimulus






5. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






7. Glossopharyngeal Nerve - taste swallow






8. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






9. 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)






10. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






11. The maintenance of water balance in the body






12. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






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






15. 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






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






17. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






18. 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






19. Hypoglossal Nerve - moves the tongue






20. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






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






22. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






23. Viscous substance between cornea and lens; transparent substance between lens and retina






24. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






25. 'Roof'






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






27. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






28. Absolute; relative






29. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






30. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






31. 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)






32. Caudate nucleus and putamen






33. Facial Nerve - moves face and salivates






34. 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






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






36. Is characteristic of indirect antagonists






37. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






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






39. Expression of traits






40. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






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






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






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






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






45. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






47. Norepinephrine and serotonin






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






49. The visual image of the world on the retina






50. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)
