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 in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






2. 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)






3. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






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






6. 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






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






8. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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

10. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






11. Controls sexual activity






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






13. Facial Nerve - moves face and salivates






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






15. 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

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






17. Projects to ventral tegmental area






18. 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)






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






20. Regulates body temperature






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






22. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






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






24. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






25. Abducens Nerve - moves eye






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






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






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






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






30. Caudate nucleus and putamen






31. Optic Nerve - sight






32. An area that combines input from diverse brain regions






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






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






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






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






37. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






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






39. Trigerminal Nerve - face sensation






40. There are 12 add more






41. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






42. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






43. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






44. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






45. The visual image of the world on the retina






46. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






47. 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)






48. 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






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






50. Opening in the iris; dilates and contracts allowing different levels of light in
