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. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






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






4. Damage to this are causes clumsiness and loss of balance






5. Norepinephrine and serotonin






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






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






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






9. Is characteristic of indirect antagonists






10. The female reproductive cycle of mammals other than primates






11. 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)






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






13. Includes the tectum and tegmentum






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






15. Functions as both a hormone and a neurotransmitter in the brain






16. Abducens Nerve - moves eye






17. Facial Nerve - moves face and salivates






18. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






19. Expression of traits






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






21. Decreasing effects of a medication due to repeated administration






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






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






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






25. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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






28. The viscous substance between cornea and lens






29. Most brain communications are with the opposite side of the body






30. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






32. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






33. In the CNS - is an amino acid that stabilizes neural activity






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






35. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






36. Caudate nucleus and putamen






37. Vestibulocochlear Nerve - hearing and balance






38. Are found in the diencephalon






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






40. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






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






43. Sign






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






45. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






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






48. Is everything anterior to the central sulcus






49. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






50. Two different presynaptic neurons/inputs to a post-synaptic cell
