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. The visual image of the world on the retina






2. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






4. 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)






5. Maintains balance/posture and coordinates body movements






6. 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






7. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






8. 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






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






10. Affect multiple receptors; highly preferential to which type of receptor they affect






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






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






13. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






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






15. 'little net'






16. 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






17. Glossopharyngeal Nerve - taste swallow






18. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






19. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






21. The viscous substance between cornea and lens






22. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






23. Pass the easiest through the blood-brain barrier






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






25. 'Roof'






26. Regulates body temperature






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






28. There are 12 add more






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






30. Expression of traits






31. Are found in the diencephalon






32. 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






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






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






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






36. 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






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






38. Facial Nerve - moves face and salivates






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






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






41. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






42. Transparent substance between lens and retina






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






44. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






45. 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






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






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






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






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






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