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. 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






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






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






4. Increasing effects/effectiveness of a medication due to repeated administration






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






6. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






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






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






9. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






10. Is characteristic of indirect antagonist drugs






11. Has neurons for reflexes






12. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






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






15. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






16. Maintains balance/posture and coordinates body movements






17. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

18. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






19. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






20. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






22. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






23. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






25. 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






26. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






27. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






29. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






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






32. Norepinephrine and serotonin






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






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






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






36. Midbrain - medulla and the pons






37. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






38. Consummatory stimulus






39. Projects to ventral tegmental area






40. Colored part of the eye






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






42. 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)






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






44. 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






45. Controls sexual activity






46. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






48. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






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