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






2. 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






3. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






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






5. Olfactory Nerve - smell






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






7. Important to motor system






8. Decreasing effects of a medication due to repeated administration






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






10. Adenine - Guanine - Thymine - Cytosine






11. 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)






12. Accessory Nerve - moves the head






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






14. 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)






15. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






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






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






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






19. 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






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






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






22. Pleasure center of the brain; discovered by Olds & Milner






23. Optic Nerve - sight






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






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






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






27. Precursor to the catecholamine neurotransmitters (DA + NE)






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






29. Is everything anterior to the central sulcus






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






31. Contains delta activity - stages III and IV






32. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






33. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






34. An area that combines input from diverse brain regions






35. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






36. The visual image of the world on the retina






37. 'Roof'






38. Supernormal






39. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






40. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






42. Mechanism whereby neurons make connections to new areas to change their connectivity






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






44. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






45. Hypoglossal Nerve - moves the tongue






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






47. Expression of traits






48. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






49. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






50. Irregular electrical activity of 13-30 Hz - state of arousal - attentive
